    Default S Type Stars Catalog



    In my neck of woods it's been cloudy for the last 8 nights, and I'm bored. So I decided to do a little research.

    Being a carbon star freak, as well as being a regular freak, I looked around for S Type Stars (very similar to carbon stars).

    Now Carbon Stars, a red giant on the asymptotic giant branch , contain more carbon than oxygen in the atmosphere.
    While S Stars, a cool giant on the asymptotic giant branch, have about the equal amount of carbon and oxygen in the atmosphere.

    Pretty neat stuff!

    So I decided I'll be adding some of these with my regular carbon observation sessions - that's if I get a decent night again.

    Anywho...

    I thought I'd share this with anyone who is interested.
    The catalog: General Catalogue of S Stars (Stephenson 1976) has 741 stars.

    Just jump onto VizieR ( VizieR ) and add the catalog.

    Enjoy...
