XMM-Newton observation of the persistent Be/NS X-ray binary pulsar RX J0440.9+4431
N. La Palombara, L. Sidoli, P. Esposito +2
Many X-ray accreting pulsars have a soft excess below 10 keV. This feature has been detected also in faint sources and at low luminosity levels, suggesting that it is an ubiquitous…
A time-variable, phase-dependent emission line in the X-ray spectrum of the isolated neutron star RX J0822-4300
A. De Luca, D. Salvetti, A. Sartori +9
RX J0822-4300 is the Central Compact Object associated with the Puppis A supernova remnant. Previous X-ray observations suggested RX J0822-4300 to be a young neutron star with a we…
Properties of Supergiant Fast X-ray Transients as observed by Swift
P. Romano, S. Vercellone, H. A. Krimm +8
We present the most recent results from our investigation on Supergiant Fast X-ray Transients, a class of High-Mass X-ray Binaries, with a possible counterpart in the gamma-ray ene…
Swift/XRT monitoring of the candidate Supergiant Fast X-ray Transient IGR J16418-4532
P. Romano, V. Mangano, L. Ducci +6
We report on the Swift monitoring of the candidate supergiant fast X-ray transient (SFXT) IGR J16418-4532, for which both orbital and spin periods are known (~3.7d and ~1250s, resp…
The progenitor of a type Ia supernova with a short delay time?
S. Mereghetti, N. La Palombara, A. Tiengo +3
HD49798/RXJ0648.0-4418 is the only known X-ray binary composed of a hot subdwarf and a massive white dwarf (M=1.28+/-0.05 Msun). This system, with an orbital period of 1.55 days, i…
X-ray and optical observations of the unique binary system HD49798/RXJ0648.0-4418
S. Mereghetti, N. La Palombara, A. Tiengo +5
We report the results of XMM-Newton observations of HD49798/RXJ0648.0-4418, the only known X-ray binary consisting of a hot sub-dwarf and a white dwarf. The white dwarf rotates ver…
