Second XMM/RGS spectrum of V2491 Cyg
Abstract
A second XMM-Newton observation of the nova V2491 Cyg was obtained on 2008 May 30.3, 49.6 days after the recent outburst and 10 days after an earlier one obtained on day 39.9 (Ness et al., ATel #1561). The exposure time in the Reflection Grating Spectrometers (RGS) was 29.8ksec, and the average count rate in the RGS1 was 2.7 counts per second (c/s). The light curve extracted from the RGS1 is less variable than during the first observation.
