Discovery of a ~30-Year-Duration Post-Nova Pulsating Supersoft Source in the Large Magellanic Cloud
G. Vasilopoulos, F. Koliopanos, T. E. Woods +3
Supersoft X-ray sources (SSS) have been identified as white dwarfs accreting from binary companions and undergoing nuclear-burning of the accreted material on their surface. Althou…
The XMM-Newton serendipitous survey. X: The second source catalogue from overlapping XMM-Newton observations and its long-term variable content
I. Traulsen, A. D. Schwope, G. Lamer +12
The XMM-Newton Survey Science Centre Consortium (SSC) develops software in close collaboration with the Science Operations Centre to perform a pipeline analysis of all XMM-Newton o…
The XMM-Newton serendipitous survey IX. The fourth XMM-Newton serendipitous source catalogue
N. A. Webb, M. Coriat, I. Traulsen +28
Sky surveys produce enormous quantities of data on extensive regions of the sky. The easiest way to access this information is through catalogues of standardised data products. {\e…
Identification of 3XMM J000511.8+634018 as a new polar at P(orb)=133.5 min -- is it inside or outside the period gap?
A. D. Schwope, H. Worpel, N. A. Webb +2
We aimed to identify the variable X-ray source 3XMM J000511.8+634018, which was serendipitously discovered through routine inspections while the 3XMM catalogue was compiled. We ana…
NuSTAR X-ray spectrum of Be-X-ray pulsar Swift J1845.7-0037: Bulk and thermal Comptonization of cyclotron seed photons in the accretion column
Filippos Koliopanos, Georgios Vasilopoulos, Michael T. Wolff
Aims: Spectral and temporal analysis of the NuSTAR observation Galactic Be-XRB Swift J1845.7-0037. during its recent outburst. Methods: For the spectral analysis we use both phenom…
The chemical composition of the accretion disk and donor star in Ultra Compact X-ray Binaries: A comprehensive X-ray analysis
Filippos Koliopanos, Mathias Peault, Georgios Vasilopoulos +1
We have analyzed the X-ray spectra of all known Ultra Compact X-ray Binaries (UCXBs), with the purpose of constraining the chemical composition of their accretion disk and donor st…
Disappearance of the Fe K emission line in Ultra Compact X-ray Binaries 4U 1543-624 and Swift J1756.9-2508
Filippos Koliopanos, Georgios Vasilopoulos, Sebastien Guillot +1
We investigate the long-term variability of the K line of iron in the spectra of two Ultra Compact X-ray Sources (UCXBs) with C/O-rich donors. We revisit archival observations b…
