Just a general question. Are there Barium Stars in SE? I found Carbon Stars at least.

I'm almost certain that there are none. Are there any barium stars in the Hipparcos catalog?

According to http://en.wikipedia.org/wiki/Barium_star , Zeta Capricorni is a barium star (or at least a prototypical one) and this star is in SE, but it's not labelled as a barium star.

Also, that star is missing it's white dwarf companion.

The other two stars listed on that page aren't in SE.

Thank you very much. I just found it as well. It is indeed there, this afternoon I wasn't able to find it (don't know why actually, maybe I didn't type it right

Many catalog stars in SE are missing companions. Anyone who feels like contributing to a complete catalog of binaries in SE is welcome to do so (I will open a thread on this shortly, which I really should have done long ago).

As far as barium stars go, it appears that they are not generally given their own spectral class separate from the traditional Morgan-Keenan system, which would explain why SE has none.
