Subject: A galactic fossil
Dear Group,

The scientific community is abuzz with a recent publication surrounding
HE 1523-0901, a star in Libra which has been dated to be 13.2 billion
years old (!) and which was created a mere 500 million years ago after
the Big Bang. The dating of this star was based on techniques similar to
carbon-14 where the abundance of thorium, uranium and other metals led
to this dramatic estimate.

The star is quite bright with an apparent magnitude of 11.1 but very low
for those (of us) at mid-northern latitudes. For an image capture of the
immediate area from early this morning, please
http://www.perseus.gr/Astro-Star-Oldest-HE-1523-0901.htm (clicking on
the hyperlinked image leads to a second image with better image scale
and which is inverted).

Clear skies!

Anthony.

PS. Thanks to Sam Wormley yesterday for helping me out with this project.

Antoni,

A very fine image! Kudos to Sam for the "heads up".

Do you suppose this example could be a "runaway" from our
friend Berkely 17? <g >

Hi Ben,

>

Thanks. I had doubts when I started the imaging due to the low altitude
and light pollution from the national highway a few kilometers back. The
gradients were the most difficult aspect of the processing.

> Kudos to Sam for the "heads up".

Actually the "heads up" belongs to Astronomy Magazine and their website
which has this star as lead story. That is what started the ball rolling.

After spending MANY hours trying to find this star (Sinbad etc), I gave
up and contacted Sam. He also had problems since there are NO references
anywhere.

Hehehehe, that is not a bad question at all !!!

Clear skies!

Anthony.

Where did you get the position of this star? SIMBAD doesn't recognize
the designation, and the link you provide appears to be in regard to a
paper about a QSO with a different HE designation. So far I haven't
been able to turn up a reference to this particular star.

Thanks,
Greg

I was pulling my hair ALL day Saturday with this star. I spent literally
many hours trying to find a reference, ANY reference to this star. Now,
to add insult to injury, the coordinates embedded within the name, are
J1950.

Anyway, I gave up and sent an email to the study's authors and I was
delighted to receive a reply before local darkness arrived which allowed
me to pursue it immediately. The coordinates I specify on the associated
web page on my site are J2000.

No problem.

Anthony.

That's cool. Thanks again Anthony (and nice image!).

For those interested the coordinates point to the star TYC 05594-0576-1
(or GSC 05594-0576).

I don't get why they felt they had to give a star with a commonly known
designation a new one, much less insist on using their designation
without telling anyone what the position is! Other than the fact this
was "published" by their PR department... (a pet peeve of mine to be sure).

Clear skies,
Greg

I can't say that I was much help, Anthony. Your image, however, is
excellent! http://www.perseus.gr/Astro-Star-Oldest-HE-1523-0901.htm

/Very/ nice work -- you /and/ Mr. Wormley. I would like to /think/ that
I could somehow /approximate/ your photograph of this star. When I read
about the star I immediately thought about trying to photograph it.
Then I remembered how the weather has been here in Maryland. And then
-- believe it or not -- I thought about you, and I would have bet that
you would do the job. Thanks!

When I first saw the subject of your post -- A galactic fossil -- I was
quite flattered; I thought you had written a little story about me.
