Chandra Multi-wavelength Project (ChaMP). II. First Results of X-ray Source Properties
D. -W. Kim, B. J. Wilkes, P. J. Green +15
We present the first results of ChaMP X-ray source properties obtained from the initial sample of 62 observations. The data have been uniformly reduced and analyzed with techniques…
Chandra Multi-wavelength Project (ChaMP). I. First X-ray Source Catalog
D. -W. Kim, R. A. Cameron, J. J. Drake +16
The Chandra Multi-wavelength Project (ChaMP) is a wide-area (~14 deg^2) survey of serendipitous Chandra X-ray sources, aiming to establish fair statistical samples covering a wide…
Modeling the NeIX Triplet Spectral Region of Capella with the Chandra and XMM-Newton Gratings
Jan-Uwe Ness
High resolution X-ray spectroscopy with the diffraction gratings of Chandra and XMM-Newton offers new chances to study a large variety of stellar coronal phenomena. A popular X-ray…
Chemical Fractionation and Abundances in Coronal Plasma
Jeremy J. Drake
Much of modern astrophysics is grounded on the observed chemical compositions of stars and the diffuse plasma that pervades the space between stars, galaxies and clusters of galaxi…
Bare Quark Stars or Naked Neutron Stars ? The Case of RX J1856.5-3754
Roberto Turolla, Silvia Zane, Jeremy J. Drake
In a cool neutron star (T < 1.e6 K) endowed with a rather high magnetic field (B > 1.e13 G), a phase transition may occur in the outermost layers. As a consequence the neutron star…
A Chandra LETGS observation of V4743 Sagittarius: A Super Soft X-ray Source and a Violently Variable Light Curve
J. -U. Ness, S. Starrfield, V. Burwitz +13
V4743 Sgr (Nova Sgr 2002 No. 3) was discovered on 20 September 2002. We obtained a 5ks ACIS-S spectrum in November 2002 and found that the nova was faint in X-rays. We then obtaine…
