A 33 year constancy of the X-ray coronae of AR Lac and eclipse diagnosis of scale height
Jeremy J. Drake, Peter Ratzlaff, Vinay Kashyap +3
Extensive X-ray and extreme ultraviolet (EUV) photometric observations of the eclipsing RS CVn system AR Lac were obtained over the years 1997 to 2013 with the Chandra X-ray Observ…
The ChaMP Extended Stellar Survey (ChESS): Photometric and Spectroscopic Properties of Serendipitously Detected Stellar X-ray Sources
K. R. Covey, M. A. Agueros, P. J. Green +9
We present 348 X-ray emitting stars identified from correlating the Extended Chandra Multiwavelength Project (ChaMP), a serendipitous wide-area X-ray survey, with the Sloan Digital…
Dark Supergiant: Chandra's Limits on X-rays from Betelgeuse
Jennifer Posson-Brown, Vinay L. Kashyap, Deron O. Pease +1
We have analyzed Chandra calibration observations of Betelgeuse (alpha Ori, M2Iab, m_V=0.58, 131 pc) obtained at the aimpoint locations of the HRC-I (8 ks), HRC-S (8 ks), and ACIS-…
Is RX J185635-375 a Quark Star?
J. J. Drake, H. L. Marshall, S. Dreizler +8
Deep Chandra LETG+HRC-S observations of the isolated neutron star candidate RX J1856.5-3754 have been analysed to search for metallic and resonance cyclotron spectral features and…
Structure of the X-ray Emission from the Jet of 3C 273
H. L. Marshall, D. E. Harris, J. P. Grimes +12
We present images from five observations of the quasar 3C 273 with the Chandra X-ray Observatory. The jet has at least four distinct features which are not resolved in previous obs…
First Light Measurements of Capella with the Low Energy Transmission Grating Spectrometer aboard the Chandra X-ray Observatory
A. C. Brinkman, C. J. T. Gunsing, J. S. Kaastra +20
We present the first X-ray spectrum obtained by the Low Energy Transmission Grating Spectrometer (LETGS) aboard the Chandra X-ray Observatory. The spectrum is of Capella and covers…
