Extinction Columns and Intrinsic X-ray Spectra of the Anomalous X-ray Pulsars
Martin Durant, Marten H. van Kerkwijk
The X-ray spectra of Anomalous X-ray Pulsars have long been fit by smooth, empirical models such as the sum of a black-body plus a power law. These reproduce the ~0.5 to 10 keV ran…
Distances to Anomalous X-ray Pulsars using Red Clump Stars
Martin Durant, Marten H. van Kerkwijk
We identify `red clump stars' - core helium-burning giants - among 2MASS stars and use them to measure the run of reddening with distance in the direction of each of the Galactic A…
Accretion Disks around Young Stars: Lifetimes, Disk Locking and Variability
Ray Jayawardhana, Jaime Coffey, Alexander Scholz +2
We report the findings of a comprehensive study of disk accretion and related phenomena in four of the nearest young stellar associations spanning 6-30 million years in age, an epo…
The infrared counterpart to the magnetar 1RXS J170849.0-400910
Martin Durant, Marten H. van Kerkwijk
We have analyzed both archival and new infrared imaging observations of the field of the Anomalous X-ray Pulsar 1RXS J170849.0-400910, in search of the infrared counterpart. This f…
Contact Binaries with Additional Components. II. A Spectroscopic Search for Faint Tertiaries
Caroline D'Angelo, Marten H. van Kerkwijk, Slavek M. Rucinski
It is unclear how very close binary stars form, given that during the pre-main-sequence phase the component stars would have been inside each other. One hypothesis is that they for…
