X-ray Development of the Classical Nova V2672 Ophiuchi with Suzaku

D. Takei, M. Tsujimoto, J. J. Drake +1

We report the Suzaku detection of a rapid flare-like X-ray flux amplification early in the development of the classical nova V2672 Ophiuchi. Two target-of-opportunity ~25 ks X-ray…

Discovery of X-ray Emission in the Old Classical Nova DK Lacertae

D. Takei, T. Sakamoto, J. J. Drake

We report the discovery of X-ray emission at the position of the old classical nova DK Lacertae using the Swift satellite. Three observations were conducted using the X-ray telesco…

Swift X-ray and UV monitoring of the Classical Nova V458 Vul (Nova Vul 2007)

J. -U. Ness, J. J. Drake, A. P. Beardmore +18

We describe the highly variable X-ray and UV emission of V458 Vul (Nova Vul 2007), observed by Swift between 1 and 422 days after outburst. Initially bright only in the UV, V458 Vu…

X-ray Eclipse Diagnosis of the Evolving Mass Loss in the Recurrent Nova U Scorpii 2010

D. Takei, J. J. Drake, M. Tsujimoto +4

We report the Suzaku detection of the earliest X-ray eclipse seen in the recurrent nova U Scorpii 2010. A target-of-opportunity observation 15 days after the outburst found a 27+/-…

X-ray Fading and Expansion in the "Miniature Supernova Remnant" of GK Persei

D. Takei, J. J. Drake, H. Yamaguchi +3

We report on a second epoch of Chandra X-ray imaging spectroscopy of the spatially-resolved old nova remnant GK Persei. An ACIS-S3 observation of 97.4 ks was conducted in November…

Detection of a Rare Supersoft Outburst Event during a Suzaku Observation of 1E0102.2-7219

D. Takei, M. Tsujimoto, S. Kitamoto +4

We report the detection of a transient X-ray source toward the Small Magellanic Cloud (SMC) using the X-ray Imaging Spectrometer (XIS) onboard the Suzaku telescope. The source was…
