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…
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,…
HV 11423: The Coolest Supergiant in the SMC
Philip Massey, Emily M. Levesque, K. A. G. Olsen +2
We call attention to the fact that one of the brightest red supergiants in the SMC has recently changed its spectral type from K0-1 I (December 2004) to M4 I (December 2005) and ba…
The Effective Temperatures and Physical Properties of Magellanic Cloud Red Supergiants: The Effects of Metallicity
Emily M. Levesque, Philip Massey, K. A. G. Olsen +3
We use the MARCS stellar atmosphere to derive the physical properties of 36 red supergiants (RSGs) in the LMC, and 39 RSGs in the SMC using moderate-resolution optical spectrophoto…
The Reddening of Red Supergiants: When Smoke Gets In Your Eyes
Philip Massey, Bertrand Plez, Emily M. Levesque +3
Deriving the physical properties of red supergiants (RSGs) depends upon accurate corrections for reddening by dust. We use our recent modeling of the optical spectra of RSGs to add…
Identification of Main Sequence Stars with Mid-Infrared Excesses Using GLIMPSE: Beta-Pictoris Analogs?
B. Uzpen, H. A. Kobulnicky, K. A. G. Olsen +23
Spitzer IRAC 3.6-8 micron photometry obtained as part of the GLIMPSE survey has revealed mid-infrared excesses for 33 field stars with known spectral types in a 1.2 sq. degree fiel…
