Taking the pulse of the shortest orbital period binary system RX J0806.3+1527
G. L. Israel, S. Covino, S. Dall'Osso +8
RX J0806.3+1527 is thought to be a 321s orbital period (the shortest known) double white dwarf binary system. According to the double degenerate binary (DDB) scenario this source i…
Variability in the quiescent state of neutron star transients
Sergio Campana
Variability studies represent a powerful tool to assess the emission mechanism(s) at work in the quiescent state of transient low mass X-ray binaries. Here we report on Chandra and…
Unveiling the multi-wavelength phenomenology of Anomalous X-ray Pulsars
GianLuca Israel, Luigi Stella, Stefano Covino +6
During 2002-2003 the number of IR-identified counterparts to the Anomalous X-ray Pulsars (AXPs) has grown to four (4U0142+614, 2E2259+584, 1E 1048-59 and 1RXS J170849-400910) out o…
Where Have All the Submillisecond Pulsars Gone?
L. Burderi, F. D'Antona, M. T. Menna +8
The existence of pulsars with spin period below one millisecond is expected, though they have not been detected up to now. Their formation depends on the quantity of matter accrete…
BeppoSAX observation of Cen X-4 in quiescence
Sergio Campana, Luigi Stella, Sandro Mereghetti +1
We report on a 61 ks BeppoSAX observation of the soft X-ray transient Cen X-4 during quiescence which allowed to study the source X-ray spectrum from ~ 0.3 keV to ~ 8 keV. A two-co…
A BeppoSAX study of the pulsating transient X0115+63: the first X-ray spectrum with four cyclotron harmonic features
A. Santangeo, A. Segreto, S. Giarrusso +9
The recurrent hard pulsating X-ray transient §was observed with \B on March 19, when the source was at a 2--10 keV flux level of 310~mCrab. We report on the high energy spect…
