Constraints on the Velocity and Spatial Distribution of Helium-like Ions in the Wind of SMC X-1 from Observations with XMM-Newton/RGS
Patrick S. Wojdowski, Duane A. Liedahl, Timothy R. Kallman
We present here X-ray spectra of the HMXB SMC X-1 obtained in an observation with the XMM observatory beginning before eclipse and ending near the end of eclipse. With the Reflecti…
Differential Emission Measure Determination of Collisionally Ionized Plasma: II. Application to Hot Stars
Patrick S. Wojdowski, Norbert S. Schulz
In a previous paper we have described a technique to derive constraints on the differential emission measure (DEM) distribution, a measure of the temperature distribution, of colli…
Ion-by-Ion DEM Determination: I. Method
Patrick S. Wojdowski, Norbert S. Schulz
We describe a technique to derive constraints on the differential emission measure (DEM) distribution, a measure of the temperature distribution, of collisionally ionized hot plasm…
Revealing the Focused Companion Wind in Cygnus X-1 with Chandra
J. M. Miller, P. Wojdowski, N. S. Schulz +5
We have analyzed a Chandra HETGS spectrum of the Galactic black hole Cygnus X-1, obtained at a source flux which is approximately twice that commonly observed in its persistent low…
Resolving the Effects of Resonant X-ray Line Scattering in Cen X-3 with Chandra
Patrick S. Wojdowski, Duane A. Liedahl, Masao Sako +2
The massive X-ray binary Cen X-3 was observed over approximately one quarter of the system's 2.08 day orbit, beginning before eclipse and ending slightly after eclipse center with…
The X-Ray Photoionized Wind in Cen X-3/V779 Cen
Patrick S. Wojdowski, Duane A. Liedahl, Masao Sako
We analyze the ASCA spectrum of the Cen X-3 X-ray binary system in eclipse using atomic models appropriate to recombination-dominated level population kinetics in an overionized pl…
