The Physical Properties and Effective Temperature Scale of O-type Stars as a Function of Metallicity. III. More Results from the Magellanic Clouds
Philip Massey, Amanda M. Zangari, Nidia I. Morrell +4
In order to better determine the physical properties of hot, massive stars as a function of metallicity, we obtained very high SNR optical spectra of 26 O and early B stars in the…
The Massive Star Content of NGC 3603
Nicholas W. Melena, Philip Massey, Nidia I. Morrell +1
We investigate the massive star content of NGC 3603, the closest known giant H II region. We have obtained spectra of 26 stars in the central cluster using the Baade 6.5-m telescop…
The Physical Properties of Red Supergiants: Comparing Theory and Observations
Philip Massey, Emily M. Levesque, Bertrand Plez +1
Red supergiants (RSGs) are an evolved stage in the life of intermediate massive stars (than than 25 solar masses). For many years, their location in the H-R diagram was at variance…
A Survey of Local Group Galaxies Currently Forming Stars: III. A Search for Luminous Blue Variables and Other H-alpha Emission-Lined Stars
Philip Massey, Reagin T. McNill, K. A. G. Olsen +5
We describe a search for H-alpha emission-lined stars in M31, M33, and seven dwarfs in or near the Local Group (IC 10, NGC 6822, WLM, Sextans B, Sextans A, Pegasus and the Phoenix…
The Coolest Stars in the Clouds: Unusual Red Supergiants in the Magellanic Clouds
Emily M. Levesque, Philip Massey, K. A. G. Olsen +1
Red supergiants (RSGs) are a He-burning phase in the evolution of moderately high mass stars (10-25 solar masses). The evolution of these stars, particularly at low metallicities,…
Bringing VY Canis Majoris Down to Size: An Improved Determination of Its Effective Tempeature
Philip Massey, Emily M. Levesque, Bertrand Plez
The star VY CMa is a late-type M supergiant with many peculiarities, mostly related to the intense circumstellar environment due to the star's high mass-loss rate. Claims have been…
