Sean J. Gunderson, Jackson Codd, Walter W. Golay +12
We present a multiwavelength analysis of the central stellar pair of Oph, components A and B. Using recent high-resolution \textit{Chandra X-ray Observatory} observations, we d…
Constraining the Number Density of the Accretion Disk Wind in Hercules X-1 Using its Ionization Response to X-ray Pulsations
P. Kosec, D. Rogantini, E. Kara +6
X-ray binaries are known to launch powerful accretion disk winds that can have significant impact on the binary systems and their surroundings. To quantify the impact and determine…
The Nature of X-Rays from Young Stellar Objects in the Orion Nebula Cluster -- A Chandra HETGS Legacy Project
Norbert S. Schulz, David P. Huenemoerder, David A. Principe +10
The Orion Nebula Cluster (ONC) is the closest site of very young ( 1 Myrs) massive star formation. The ONC hosts more than 1600 young and X-ray bright stars with masses rangi…
Chandra HETG X-ray Spectra and Variability of Aqr, a Cas-type Be star
David P. Huenemoerder, Pragati Pradhan, Claude R. Canizares +7
High-resolution X-ray spectra of Aqr, a Cas-type star, obtained with the Chandra/HETG grating spectrometer, revealed emission lines of H-like ions of Mg, Si, S, and Fe,…
