This page is still under development and consists mostly of lists of subjects in stellar astrophysics. I will add more catalogs and references as time permits.

This page is intended to provide a resource list for material in each subject.

Stars

HR Diagram
Stellar Evolution and the HR Diagram

Population I Stars: chemical composition similar to the Sun - relatively young
Population II Stars: metal poor - as old as the galaxy

Supergiants (Ia and Ib)
Giants (II, III)
Dwarfs: Main sequence stars (V)
Subdwarfs (VI) [metal-poor population II stars]
White dwarfs (VII)
Peculiar stars - outside the MK classification
- Carbon stars (giant stars having intense molecular bands due to Carbon)
- S stars (giant stars having strong bands due to ziconium, yttrium, and barium)
- Ap and Am stars (main sequence stars having intense metalic lines)
- Oe and Be stars (hot stars with emmission lines - from tenuous envelopes of gas)
- Subdwarfs (VI) (population II stars)
- Symbiotic stars (with absorption and emmission lines - probably binary stars)
