Continuing X-ray Emission of Nova Vul 2007
Abstract
We report a new observation of Nova Vul 2007 (S. Nakano, IAUC 8861) obtained by the Swift X-ray Telescope (XRT) on 2008 June 18. The nova was detected at count rate of 0.023 count/s, representing a decline by a factor of 3 compared with Swift XRT observations obtained during 2007 November- December, and by about 50% compared with the previous observation obtained on 2007 December 27. The XRT spectrum is significantly softer than during the earlier epoch, with a ratio of X-ray counts in the 1-10 keV band to those in the 0.3-1 keV band having declined from about 1.0 to 0.4.
