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,…
Physical Properties of Red Supergiants
Philip Massey, Bertrand Plez, Emily M. Levesque +3
Red supergiants (RSGs) are an evolved stage in the life of intermediate massive stars (<25Mo). For many years their location in the H-R diagram was at variance with the evolutionar…
The Host Galaxy of GRB 060505: Host ISM Properties
Emily M. Levesque, Lisa J. Kewley
We investigate the ISM environment of GRB 060505. Using optical emission-line diagnostic ratios, we compare the ISM properties of the GRB 060505 host region with the hosts of unamb…
Late-Type Red Supergiants: Too Cool for the Magellanic Clouds?
Emily M. Levesque, Philip Massey, K. A. G. Olsen +1
We have identified seven red supergiants (RSGs) in the Large Magellanic Cloud (LMC) and four RSGs in the Small Magellanic Cloud (SMC), all of which have spectral types that are con…
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…
