High-resolution X-ray spectroscopy of the ultracompact LMXB pulsar 4U 1626-67
Miriam I. Krauss, Norbert S. Schulz, Deepto Chakrabarty +2
[abridged] We report results from four recent observations of the ultracompact LMXB pulsar 4U 1626-67. All the observations obtained high-resolution X-ray spectra of the system, tw…
X-ray Variability in the Young Massive Triple theta2 Ori A
Norbert S. Schulz, Paola Testa, David P. Huenemoerder +2
Massive stars rarely show intrinsic X-ray variability. The only O-stars credited to be intrinsically variable are theta1 Ori C due to effects from magnetic confinement of its wind,…
Extraordinarily Hot X-ray Emission from the 09 Emission Line Star HD 119682
C. E. Rakowski, N. S. Schulz, S. J. Wolk +1
We present new optical and X-ray observations to show that the X-ray source 1 WGA J1346.5--6255 previously associated with the SNR G309.2--0.6 can be unequivocally identified with…
High-Resolution X-ray Spectroscopy of the Interstellar Medium II: Neon and Iron Absorption Edges
Adrienne M. Juett, Norbert S. Schulz, Deepto Chakrabarty +1
We present high-resolution spectroscopy of the neon K-shell and iron L-shell interstellar absorption edges in nine X-ray binaries using the High Energy Transmission Grating Spectro…
Determining the Nature of the SS 433 Binary Using an X-ray Spectrum During Eclipse
Laura A. Lopez, Herman L. Marshall, Claude R. Canizares +2
We test the physical model of the relativistic jets in the galactic X-ray binary SS 433 proposed in our previous paper using additional observations from the Chandra High Energy Tr…
The Kinematic and Plasma Properties of X-ray Knots in Cassiopeia A from the Chandra HETGS
J. S. Lazendic, D. Dewey, N. S. Schulz +1
We present high-resolution X-ray spectra from the young supernova remnant Cas A using a 70-ks observation taken by the Chandra High Energy Transmission Grating Spectrometer (HETGS)…
Star Formation in the Era of the Three Great Observatories
Scott J. Wolk, Norbert Schulz, John Stauffer +6
This paper summarizes contributions and suggestions as presented at the Chandra Workshop Star Formation in the Era of Three Great Observatories conducted in July 2005. One of the d…
