The HR diagram in the infrared (K, V-K) for the RR Lyrae stars of the globular cluster M3 is derived using published photometric data. Also shown is the relation - versus log PF for the RR Lyrae stars in the same cluster. Those stars which are the most evolved from ZAHB are well ...

With the aid of these stellar models we analyze the HR diagram (HRD) of supergiant stars in the LMC by Fitzpatrick & Garmany (1990) and that of supergiant stars in the Milky Way by Blaha & Humphreys (1989). Particular attention is paid to the star counts across the HRD, the stars in...
I argue that this is an empirical HR diagram for the WN stars because for each sequence (weak and strong); there is a linear correlation between temperature and the equivalent width ratio, and an inverse linear correlation between the absolute visual magnitude and the EW_{lambda 5412}. (This...

K StarsLate StarsIt is found that nonthermal radio emission is associated with stars in very specific locations on the HR diagram. The four classes of objects are typified by early-type mass-loss stars (05/WR), late-type giants and supergiants (M2II), subgiant K-stars (KO IV–III), ...
