Phase resolved spectroscopy of the accreting millisecond X-ray pulsar SAX J1808.4-3658 during the 2008 outburst
R. Cornelisse, P. D'Avanzo, T. Munoz-Darias +6
aims: We obtained phase-resolved spectroscopy of the accreting millisecond X-ray pulsar SAX J1808.4-3658 during its outburst in 2008 to find a signature of the donor star, constrai…
XMM-Newton discovery of 2.6 s pulsations in the soft gamma-ray repeater SGR 1627-41
P. Esposito, A. Tiengo, S. Mereghetti +6
After nearly a decade of quiescence, the soft gamma-ray repeater SGR 1627-41 reactivated on 2008 May 28 with a bursting episode followed by a slowly decaying enhancement of its per…
XMM-Newton observations of IGR J00291+5934: signs of a thermal spectral component during quiescence
Sergio Campana, Luigi Stella, Gianluca Israel +1
We present X-ray observations of the transient accretion-powered millisecond pulsar IGR J00291+5934 during quiescence. IGR J00291+5934 is the first source among accretion powered m…
IGRJ16479-4514: the first eclipsing supergiant fast X-ray transient?
E. Bozzo, L. Stella, G. Israel +2
Supergiant fast X-ray transients are a new class of high mass X-ray binaries recently discovered with INTEGRAL. Hours long outbursts from these sources have been observed on numero…
Chandra and XMM-Newton observations of the low-luminosity X-ray pulsators SAX J1324.4-6200 and SAX J1452.8-5949
Ramanpreet Kaur, Rudy Wijnands, Alessandro Patruno +5
We present results from our Chandra and XMM-Newton observations of two low-luminosity X-ray pulsators SAX J1324.4-6200 and SAX J1452.8-5949 which have spin-periods of 172 s and 437…
The 2008 May burst activation of SGR 1627-41
P. Esposito, G. L. Israel, S. Zane +16
In May 2008 the soft gamma-ray repeater SGR 1627-41 resumed its bursting activity after nearly a decade of quiescence. After detection of a bright burst, Swift pointed its X-ray te…
