GRB 070714B - Discovery of the Highest Spectroscopically Confirmed Short Burst Redshift
J. F. Graham, A. S. Fruchter, A. J. Levan +10
We detect the optical afterglow and host galaxy of GRB 070714B. Our observations of the afterglow show an initial plateau in the lightcurve for approximately the first 5 to 25 minu…
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…
