Stellar or Non-Stellar Light? Determining Near-Infrared Contamination in Low Mass X-ray Binaries [PDF]

, 2009
Low-mass X-ray binary (LMXB) systems are comprised of a low-mass, K or M dwarflike star orbiting a compact object. Stellar black hole masses and their distributions are important inputs for binary evolution and supernova models.

No disks around low-mass stars and brown dwarfs in the young sigma Orionis cluster? [PDF]

, 2001
We report on the analysis of 2MASS near-infrared data of a sample of low-mass stars and brown dwarfs in the sigma Orionis cluster. Youth and cluster membership have been spectroscopically confirmed using the Li I spectral line. We find little evidence in
