How rapidly do neutron stars spin at birth? Constraints from archival X-ray observations of extragalactic supernovae
Rosalba Perna, Roberto Soria, Dave Pooley +1
Traditionally, studies aimed at inferring the distribution of birth periods of neutron stars are based on radio surveys. Here we propose an independent method to constrain the puls…
Transient Phenomena in Anomalous X-ray Pulsars
GianLuca Israel, Federico Bernardini, Marta Burgay +4
In 2003 a previously unpulsed Einstein and ROSAT source cataloged as soft and dim (Lx of few 10^33 ergs) thermal emitting object, namely XTE J1810-197, was identified as the first…
Very deep X-ray observations of the Anomalous X-ray Pulsar 4U 0142+614
N. Rea, E. Nichelli, G. L. Israel +8
We report on two new XMM-Newton observations of the Anomalous X-ray Pulsar (AXP) 4U 0142+614 performed in March and July 2004, collecting the most accurate spectrum for this source…
The optical counterpart of IGR J00291+5934 in quiescence
P. D'Avanzo, S. Campana, S. Covino +3
The recent (December 2004) discovery of the sixth accretion-powered millisecond X-ray pulsar IGR J00291+5934 provides a very good chance to deepen our knowledge of such systems. Al…
Multicolor observations of the afterglow of the short/hard GRB 050724
D. Malesani, S. Covino, P. D'Avanzo +19
New information on short/hard gamma-ray bursts (GRBs) is being gathered thanks to the discovery of their optical and X-ray afterglows. However, some key aspects are still poorly un…
On the maximum efficiency of the propeller mass-ejection mechanism
M. Falanga, E. Bozzo, L. Stella +3
Aims. We derive simple estimates of the maximum efficiency with which matter can be ejected by the propeller mechanism in disk-fed, rotating magnetic neutron stars. Some binary evo…
