X-ray Spectroscopy of the 2006 Outburst of RS Oph
Thomas Nelson, Marina Orio, Joseph P. Cassinelli +3
We present the X-ray grating spectra of the recurrent nova RS Ophiuchi during its 2006 outburst, obtained with the XMM-Newton and Chandra observatories. Two weeks after optical max…
Variability and multi-periodic oscillations in the X-ray light curve of the classical nova V4743 Sgr
E. Leibowitz, M. Orio, R. Gonzalez-Riestra +5
The classical nova V4743 Sgr was observed with XMM-Newton for about 10 hours on April 4 2003, 6.5 months after optical maximum. At this time, this nova had become the brightest sup…
A New View of the Supersoft X-Ray Source Cal 87 Observed with XMM-Newton
Marina Orio, Ken Ebisawa, John Heise +1
Cal 87 was observed with XMM-Newton in April of 2003. The source shows a rich emission line spectrum, where lines can be identified if they are red-shifted by 700-1200 km/s. These…
