The spectral and temporal properties of an Ultra-Luminous X-ray source in NGC 6946
A. Senorita Devi, R. Misra, K. Shanthi +1
We report variability of the X-ray source, X-7, in NGC 6946, during a 60 ksec Chandra observation when the count rate decreased by a factor of ~1.5 in ~5000 secs. Spectral fitting…

The dependence of the estimated luminosities of ULX on spectral models
A. Senorita Devi, R. Misra, V. K. Agrawal +1
Data from {\it Chandra} observations of thirty nearby galaxies were analyzed and 365 X-ray point sources were chosen whose spectra were not contaminated by excessive diffuse emissi…

New Measurements of Orbital Period Change in Cygnus X-3
N. S. Singh, S. Naik, B. Paul +3
A nonlinear nature of the binary ephemeris of Cygnus X-3 indicates either a change in the orbital period or an apsidal motion of the orbit. We have made extended observations of Cy…
