The Effects of Clumps in Explaining X-ray Emission Lines from Hot Stars
J. P. Cassinelli, R. Ignace, W. L. Waldron +3
It is now well established that stellar winds of hot stars are fragmentary and that the X-ray emission from stellar winds has a strong contribution from shocks in winds. Chandra hi…
X-Atlas: An Online Archive of Chandra's Stellar High Energy Transmission Gratings Observations
Owen W. Westbrook, Nancy Remage Evans, Scott J. Wolk +6
The high-resolution X-ray spectroscopy made possible by the 1999 deployment of the Chandra X-ray Observatory has revolutionized our understanding of stellar X-ray emission. Many pu…
Phase-dependent X-ray observations of the beta Lyrae system: No eclipse in the soft band
R. Ignace, L. M. Oskinova, W. L. Waldron +2
We report on observations of the eclipsing and interacting binary beta Lyrae from the Suzaku X-ray telescope. This system involves an early B star embedded in an optically and geom…
X-ray Emission from Magnetically Torqued Disks of Oe/Be Stars
Q. Li, J. P. Cassinelli, J. C. Brown +2
We focus attention on the Oe/Be stars to test the concept that the disks of these stars form by magnetic channeling of wind material toward the equator. Calculations are made of th…
An Extensive Collection of Stellar Wind X-ray Source Region Emission Line Parameters,Temperatures, Velocities, and Their Radial Distributions as Obtained from Chandra Observations of 17 OB Stars
Wayne L. Waldron, Joseph P. Cassinelli
Chandra high energy resolution observations have now been obtained from numerous non-peculiar O and early B stars. The observed X-ray emission line properties differ from pre-launc…
High Resolution X-ray Spectra of the Brightest OB Stars in the Cygnus OB2 Association
W. L. Waldron, J. P. Cassinelli, N. A. Miller +2
The Cygnus OB2 Association contains some of the most luminous OB stars in our Galaxy, the brightest of which are also among the most luminous in X-rays. We have obtained a Chandra…
