The very short supersoft X-ray state of the classical nova M31N 2007-11a
M. Henze, W. Pietsch, G. Sala +9
Short supersoft X-ray source (SSS) states (durations < 100 days) of classical novae (CNe) indicate massive white dwarfs that are candidate progenitors of supernovae type Ia. We car…
The first two transient supersoft X-ray sources in M 31 globular clusters and the connection to classical novae
M. Henze, W. Pietsch, F. Haberl +12
Classical novae (CNe) have been found to represent the major class of supersoft X-ray sources (SSS) in our neighbour galaxy M 31. We determine properties and evolution of the two f…
The 2007 outburst of the X-ray binary XTE J1856+053
G. Sala, J. Greiner, M. Ajello +1
On 28 February 2007 a new outburst of the previously known transient source XTE J1856+053 was detected with RXTE/ASM. We present here the results of an XMM-Newton (0.5-10.0 keV) Ta…
Very fast optical flaring from a possible new Galactic magnetar
A. Stefanescu, G. Kanbach, A. Słowikowska +3
Highly luminous rapid flares are characteristic of processes around compact objects like white dwarfs, neutron stars or black holes. In the high energy regime of X- and gamma-rays,…
New XMM-Newton analysis of three bright X-ray sources in M31 globular clusters, including a new black hole candidate
R. Barnard, H. Stiele, D. Hatzidimitriou +6
We present detailed analysis of three globular cluster X-ray sources in the XMM-Newton extended survey of M31. The X-ray counterpart to the M31 globular cluster Bo 45 (XBo 45) was…
