Chandra ACIS and Newton EPIC Observations of the X-ray Luminous SN1978K in NGC 1313
Eric M. Schlegel, Albert Kong, Philip Kaaret +2
We describe an observation of the X-ray luminous SN1978K in NGC 1313 using the ACIS detector on Chandra and an archival Newton EPIC observation. The models that provided good fits…
Chandra Studies of the X-ray Point Source Luminosity Functions of M31
A. K. H. Kong, R. Di Stefano, M. R. Garcia +1
Three different M31 disk fields, spanning a range of stellar populations, were observed by Chandra. We report the X-ray point source luminosity function (LF) of each region, and th…
Transient supersoft X-ray emission from V751 Cyg during the optical low-state
J. Greiner, G. H. Tovmassian, R. DiStefano +4
We have observed V751 Cyg with the ROSAT HRI during its recent optical low state and clearly detect it at a count rate of 0.015 cts/s. The X-ray intensity is a factor of ~20 higher…
Relation between supersoft X-ray sources and VY Scl stars
Jochen Greiner, Rosanne DiStefano
In a recent ROSAT observation, taken during its optical low state, we found that the VY Scl star V751 Cyg was a highly luminous source of soft X-rays. The ROSAT HRI count rate of V…
