Media Resources for Carbon Stars new
      #5528980 - 11/19/12 10:27 PM

Carbon stars are fun to look at. Their atmosphere has carbon components that absorb bluish light, leaving reds and oranges to tint the star's color.

I know the Sky and Telescope "Pocket Sky Atlas" identifies 55 carbon stars on its charts using a (c) label. In another thread (click here) I posted a listing of exactly what those 55 stars are.

What other media resources are there for carbon star observers? Please post your replies for others to consider.

Off the top of my head Jim, the two I know of are the Carbon Star observing programs of the Astronomical League and the Saguarro Astronomical Club. However, I've found quite a few in each that don't show visible spectral color typical of carbon stars. There's much overlap in the three lists, but with a little time you can combine them into a list customized to your desire.

look up info on colorful double stars, and there usually is a list of red / carbon stars.
there was an article receintly in one of the magz called "blood in the sky", just can't remember which magz.

Sky Catalogue 2000.0, Volume 2, Variable Star section. Just scan down the spectrum column and look for the C classification.

Another resource would be Burnham's Celestial Handbook, variable star list in each constellation, although here one would be looking for the spectral classifications of R or N which were superceded by the newer classification of C.

Less daunting lists can be found in Webb's Celestial Objects for Common Telescopes in the index under Variable Stars and Stars with Interesting Spectra, though again, as with Burnham's, the spectral classification would be R or N, not the newer C.

Print media, old school stuff, I know, but I am a and I tend to turn to my library first, computer second when searching for information.

I think Stephenson's Catalog of Cool Galactic Carbon Stars might well be the standard reference.

Wow. Great. Thanks...

And quoting from another thread, let's add:

The RASC Observer's Handbook 2013 has a list of about 135 carbon stars with names (e.g. WZ Cas) and RA/Dec, with magnitude ranges. The PC planetarium software Earth Centred Universe (ECU) Handbook Edition, free to every Handbook recipient, has this list already loaded. http://rasc.ca/handbook

Cool beans about the RASC handbook, I might need to get a copy.

If you get a copy, I guarantee you won't regret it. It's an incredibly handy reference book, and full of many fascinating tidbits.

Glenn, et al;

I used Stephanson's list when I made up the SAC list and added famous stars such as Antares and like that. I remember Brian Skiff giving me a number for B-V when sorting the list, I think I made the cut off at 2.5 or something like that. There are some stars on the list that show little color, I need to revise the list and just have not made the time.

Clear skies;
Steve Coe
