Phase-resolved spectroscopic analysis of the eclipsing black hole X-ray binary M33 X-7: System properties, accretion, and evolution
V. Ramachandran, L. M. Oskinova, W. -R. Hamann +10
M33 X-7 is the only known eclipsing black hole high mass X-ray binary. The system is reported to contain a very massive O supergiant donor and a massive black hole in a short orbit…
Mass loss rates from mid-IR excesses in LMC and SMC O stars
D. Massa, A. W. Fullerton, R. K. Prinja
We use a combination of BVJHK and Spitzer [3.6], [5.8] and [8.0] photometry to determine IR excesses for a sample of 58 LMC and 46 SMC O stars. This sample is ideal for determining…
The Cosmic Origins Spectrograph: On-Orbit Instrument Performance
S. Osterman, J. Green, C. Froning +31
The Cosmic Origins Spectrograph (COS) was installed in the Hubble Space Telescope in May, 2009 as part of Servicing Mission 4 to provide high sensitivity, medium and low resolution…
The Infrared Properties of Massive Stars in the Magellanic Clouds
A. Z. Bonanos, D. J. Lennon, D. L. Massa +9
We present results of our study of the infrared properties of massive stars in the Large and Small Magellanic Clouds, which are based on the Spitzer SAGE surveys of these galaxies.…
Looking for Mister Goodstar (A preliminary analysis of stars with S IV, V and VI wind lines)
D. Massa
The winds of stars with very specific temperatures and luminosities are ideal for determining the magnitude and nature of mass loss in OB stars. I identify these stars and analyze…
An Analysis of the Shapes of Ultraviolet Extinction Curves. IV. Extinction without Standards
Edward L. Fitzpatrick, Derck Massa
We present a new method for deriving UV-through-IR extinction curves, based on the use of stellar atmosphere models to provide estimates of the intrinsic (i.e., unreddened) stellar…
