The Luminosity Function of Red Supergiants in M31
Kathryn F. Neugent, Philip Massey, Cyril Georgy +5
The mass-loss rates of red supergiant stars (RSGs) are poorly constrained by direct measurements, and yet the subsequent evolution of these stars depends critically on how much mas…
The Wolf-Rayet Content of the Galaxies of the Local Group and Beyond
Kathryn F. Neugent, Philip Massey
Wolf-Rayet stars (WRs) represent the end of a massive star's life as it is about to turn into a supernova. Obtaining complete samples of such stars across a large range of metallic…
The Discovery of QSOs Behind M31 and M33
Philip Massey, Kathryn F. Neugent, Emily M. Levesque
We report the discovery of 11 newly found quasars behind the stellar disks of the spiral galaxies M31 and M33 in the fields covered by the Local Group Galaxy Survey. Their redshift…
Binary Red Supergiants II: Discovering and Characterizing B-type Companions
Kathryn F. Neugent, Emily M. Levesque, Philip Massey +1
The percentage of massive main sequence OB stars in binary systems is thought to be as high as 100%. However, very few Galactic binary red supergiants (RSGs) have been identified,…
