SAXJ0635.2 + 0533 is a binary pulsar with a very short pulsation period ( P = 33 . 8 ms) and a high long-term spin down ( ˙ P > 3 . 8 × 10 − 13 s s − 1 ), which suggests a rotation-powered (instead of an accretion-powered) nature for this source. While it was discovered at a ﬂux level around 10 − 11 erg cm − 2 s − 1 , between 2003 and 2004, this source was detected with XMM–Newton at an average ﬂux of about 10 − 13 erg cm − 2 s − 1 ; moreover, the ﬂux varied by over one order of magnitude on…

Soft excess in the quiescent Be/X-ray pulsar RX J0812.4–3114
• Physics

We report a 72 ks XMM–Newton observation of the Be/X-ray pulsar (BeXRP) RX J0812.4–3114 in quiescence ($L_X \approx 1.6\times 10^{33}\, \mathrm{erg\, s^{-1}}$). Intriguingly, we find a
Kinematic distinction of the two subpopulations of X-ray pulsars
The population of Be/X-ray binaries shows strong evidence of bimodality, especially in the spin period of neutron stars. Several physical mechanisms may produce this bimodality. The most favored
