KEPLER WATCHES STELLAR DANCERS IN THE PLEIADES CLUSTER
Like cosmic ballet dancers, the stars of the Pleiades
cluster are spinning. But these celestial dancers are
all twirling at different speeds. Astronomers have
long wondered what determines the rotation rates
of these stars.
By watching these stellar dancers, NASA’s
Kepler space telescope has helped amass the most
complete catalog of rotation periods for stars in a
cluster. This information can help astronomers
gaina insight into where and how planets form
around these stars, and how such stars evolve.
“We hope that by comparing our results to
other star clusters, we will learn more about the
relationship between a star’s mass, its age, and even
the history of its solar system,” said Luisa Rebull,
a research scientist at the Infrared Processing and
Analysis Center at Caltech in Pasadena, California.
She is the lead author of two new papers and a co-
author on a third paper about these findings, all
being published in the Astronomical Journal.
The Pleiades star cluster is one of the closest
and most easily seen star clusters, residing just
445 light-years away from Earth, on average. At
about 125 million years old, these stars—known
individually as Pleiads—have reached stellar
“young adulthood.” In this stage of their lives,
the stars are likely spinning the fastest they ever
will.
As a typical star moves further along into
adulthood, it loses some zip due to the copious
emission of charged particles known as a stellar
wind (in our solar system, we call this the solar
wind). The charged particles are carried along
the star’s magnetic fields, which overall exerts a
braking effect on the rotation rate of the star.
Rebull and colleagues sought to delve deeper
into these dynamics of stellar spin with Kepler.
Given its field of view on the sky, Kepler observed
approximately 1,000 stellar members of the
Pleiades.
Kepler measurements of starlight infer the spin
rate of a star by picking up small changes in its
brightness. These changes result from “starspots”
which, like the more-familiar sunspots on our Sun,
form when magnetic field concentrations prevent
the normal release of energy at a star’s surface.
The affected regions become cooler than their
surroundings and appear dark in comparison.
As stars rotate, their starspots come in and out of
Kepler’s view, offering a way to determine spin rate.
Unlike the tiny, sunspot blemishes on our middle-
aged Sun, starspots can be gargantuan in stars as
young as those in the Pleiades because stellar youth
is associated with greater turbulence and magnetic
activity. These starspots trigger larger brightness
decreases, and make spin rate measurements easier
to obtain.
During its observations of the Pleiades, a clear
pattern emerged in the data: More massive stars
tended to rotate slowly, while less massive stars
tended to rotate rapidly. The big-and-slow stars’
periods ranged from one to as many as 11 Earth
days. Many low-mass stars, however, took less than
a day to complete a pirouette. (For comparison, our
sedate Sun rotates just once every 26 days.)
FUN FACT. The Japanese word for Pleiades is
“Subaru.” Sound familiar? That six-star emblem on
all Subaru cars is none other than a stylized version
of the Pleiades cluster, as seen with the naked eye,
binoculars, or a low-power telescope.

THE VEGETABLE WAR IN THE
PARSONAGE
MOUNTAIN VIEWPOINTS
On life, death, and Respecting others
Lately, a little bit of tension
has developed between the Gracious Mistress of
the Parsonage and myself. It has been a long time
coming and I am afraid it has arrived.
After decades of being married, and I am not
quite sure which decades, it has all come down to
this one thing. Vegetables.
At my age, I think I should be over all this
nonsense of what my wife calls “eating healthy.”
Who says eating vegetables is healthy?
Well, my wife says it. It must be true or she would
not say it. I am not quite sure how to deal with this
rather delicate situation. After all, she is the one
that prepares meals and I am the one that devours
the meals.
She believes that because she prepares the meals,
she should be the one to decide what those meals
should be made up of.
Me, on the other hand, and I am not sure it is
the right hand or the left, believe that because I
devour those meals I should have something to
say in what those meals really are.
Up until recently, I have not made a big issue of
this, but I think the time has come for me to put
my foot down. Vegetables and I are parting ways.
It is not that I do not like any vegetables. There are
a few I enjoy munching on, like corn, lima beans
and carrot cake.
That last one gets me in trouble every time. I
insist that carrots are a vegetable of which my
wife cannot argue. It is the cake part that she says
disqualifies it for being a vegetable. I say since the
word “carrot” comes before “cake” it defines what
it really is. A carrot is a vegetable.
You can appreciate, I’m sure, the dilemma I am in.
“At your delicate age,” she says rather sarcastically,
“you should be eating healthy.”
My rebuttal is simply that all my life I have been
eating healthy now I should be entering the stage
when I can eat what I want to eat and what makes
me happy rather it is healthy or not.
Of course, my idea of healthy does not correlate
with her idea of healthy. I understand that, but I
also understand it is my health.
Last month I went to the doctor for my annual
visit. As usual, he found nothing wrong with me
and in a little bit of desperation he said, “Someone
your age should have something wrong with
them.” With all of his doctoring expertise, he
could not find anything wrong with me, which
means I must be healthy.
Therefore, I say, somebody my age with nothing
wrong with them should be able to eat exactly
what he or she wants to eat.
I remember all my life whenever going out to eat;
I always made sure I ordered a salad to go along
with my meal. It was not because I really liked
salads, but it was supposed to be healthy for you. I
honestly believe I have eaten enough salads in my
lifetime to last the rest of my life.
Then the argument comes from the other side of
the house. “The reason the doctor doesn’t find
anything wrong with you,” she says rather sternly,
“is because you’ve been eating healthy vegetables
all your life.”
I suppose there is some kudos in that argument.
“Don’t you remember,” she said, “that Eve used an
apple to cause Adam to fall into sin?”
Well, I had to think about that one. There is no
concrete evidence that it was an apple tree, but I
was not in any position to challenge her theology
at that moment.
Recently we have come to somewhat of a stalemate
on this. She accepts the fact that I will not eat
broccoli at all or any green leafy stuff on a regular
basis. I think it is good for me just to go step-by-
step in this regard.
A recent news story reported of people getting
sick after eating some leafy vegetables at some
restaurant buffet, and I remind her of this every
chance I get. “I just,” I try to explain to her, “want
to be careful about what I eat so I don’t get sick.”
That argument always brings on one of her glaring
looks in my direction. Then she will sigh rather
deeply and say in that sweet little voice of hers, “I
want you to be healthy so that you’re around as
long as possible.”
After she says that, I have lost the argument. Of
course, I want to be around as long as possible.
And so, I promised her that every month I would
eat one helping of a healthy vegetable but a
vegetable of my choosing.
She smiles, knowing that she’s got me. The thing
about this “got me” moment is there is nothing I
can do about it. All arguments aside, she got me.
I am sure the Bible has a lot to say about eating
healthy. One verse that comes to my mind along
this line is, “Whether therefore ye eat, or drink,
or whatsoever ye do, do all to the glory of God” (1
Corinthians 10:31).
If my body is the temple of God, as the Bible
declares, I need to treat it with respect and
whatever I do, I need to do it to the glory of God.

Many years ago, I met a man named Charlie
Locke who was a live-in caretaker for the Angeles
Forest Service at a camp called Oakwilde. Oakwilde
is about a five mile walk from the closest road.
I met him when I was leading a hiking class
through Pasadena City College, taking the class
down the old CCC road from the Angeles Crest
Highway, into the Arroyo Seco, to Oakwilde. Little
did I know that the trail was washed out, and half
the class turned back. The rest of us hiked right
down the ridgeline into the camp and there we
met Charlie, living there with his many tents and
many dogs. Charlie was your stereo-typical hermit
mountain man, living the good life naturally and
rustically.
We all enjoyed meeting this mountain man and
talking with him about his viewpoints on life, gold-
panning, Irish coffee, and many other topics.
I’d visit Charlie a few times over the next few
years before he had a medical emergency and had
to be airlifted out of the campsite, never to return.
Charlie told me that one day in his remote part
of the canyon, an angry man with a dog came by
and told Charlie that he was sick of life and that
he was going to kill himself. The man climbed up
a nearby cliff where he informed Charlie he was
going to jump. Charlie told me that he had to think
quickly.
“What about your dog?” yelled Charlie. “Who’s
going to take care of Sampson?” The man
responded that he was going to kill himself, not
responding to Charlie.
“And are you just going to jump right there?”
Charlie demanded. “You mean to tell me that
you’re going to hit those rocks and let me or
someone else clean up the mess?” Charlie acted as
if he was angry. The man still seemed angry but
seemed to be thinking about it.
“That’s not very considerate,” said Charlie. “I
mean, if you’re going to kill yourself, you should at
least get a home for your dog, and figure out how to
do it so it doesn’t inconvenience other people.” The
man remained on the cliff.
“I really don’t want you to jump,” continued
Charlie. “I don’t have the time or energy to clean
up your body and then go get the police or sheriff
and then find your family. I mean, I’ve got to repair
my tent, and I need to clean out the fire pits for the
weekend hiker, and the rangers want me to keep
the outhouse cleaned up for the hikers.” He was
silent for a bit.
“I’ll tell you what,” said Charlie. “You can go
ahead and kill yourself, but just not today. Why
don’t you give me a hand with my chores, and
when we’re done, I’ll make us some soup and
potatoes and we can talk about it. What do you
say?”
Charlie says that the man slowly came off the
cliff, and then he followed Charlie back to the camp
a short distance away. Charlie began by giving him
a tool to cut down some of the tall wild grasses
around the camp that were potential fire hazards.
When the man was done, Charlie gave him another
task.
Charlie told me that they had a very satisfying
dinner, and neither brought up the suicide attempt
again. The man stayed with Charlie a few days,
helping out with chores, before he disappeared
back down the trail and into the city.
“You see,” said Charlie, “perhaps all the man
needed was someone to listen to him, and to make
him feel important, that his life meant something.
I didn’t do anything special, just treated him like
everyone ought to be treated.”
