XMM-Newton observations of XTE J1817-330 and XTE J1856+053
Gloria Sala, Jochen Greiner, Eugenio Bottacini +1
The black hole candidate XTE J1817-330 was discovered in outburst on 26 January 2006 with RXTE/ASM. One year later, on 28 February 2007, another X-ray transient discovered in 1996,…
GRO J1655-40: from ASCA and XMM-Newton Observations
Xiao-Ling Zhang, Shuang Nan Zhang, Gloria Sala +3
We have analysed four ASCA observations (1994--1995, 1996--1997) and three XMM-Newton observations (2005) of this source, in all of which the source is in high/soft state. We model…
XMM-Newton Observations of Recent Galactic Novae
Margarita Hernanz, Gloria Sala
We report on the observations of five recent galactic classical novae, performed with XMM-Newton. Some of them show emission in the whole range from 0.2 to 8.0 keV, up to 3 years a…
The Turn-off of Classical Novae Observed Through X-rays: Models versus ROSAT Observations of V1974 Cyg
Gloria Sala, Margarita Hernanz
Detection of X-ray emission from classical novae in their post-outburst stages provides crucial information about the nova phenomenon. The soft X-ray emission gives a direct insigh…
