X-ray Energy Spectra of the Super-soft X-ray Sources CAL87 and RXJ0925.7-4758 Observed with ASCA
K. Ebisawa, K. Mukai, T. Kotani +7
We report observation results of the super-soft X-ray sources (SSS) CAL87 and RXJ0925.7-4758 with the X-ray CCD cameras (Solid-state Imaging Spectrometer; SIS) on-board the ASCA sa…
The X-ray spectra of VW Hydri during the outburst cycle
H. W. Hartmann, P. J. Wheatley, J. Heise +2
We report six BeppoSAX X-ray observations of VW Hydri during and after the outburst of Sep 23 1998. The outburst flux is lower than the quiescent flux in the entire observed energy…
A BeppoSAX observation of the supersoft source 1E 0035.4-7230
P. Kahabka, A. N. Parmar, H. W. Hartmann
Results from a 37,000 s BeppoSAX Low-Energy Concentrator Spectrometer (LECS) observation of the supersoft source SMC 13 (=1E 0035.4-7230) in the Small Magellanic Cloud are reported…
A BeppoSAX LECS observation of the super-soft source CAL83
A. N. Parmar, P. Kahabka, H. W. Hartmann +1
We report on a BeppoSAX Low-Energy Concentrator Spectrometer (LECS) observation of the super-soft source (SSS) CAL83. The X-ray emission in SSS is believed to arise from nuclear bu…
