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…
"Orphan" afterglows in the Universal Structured Jet Model for gamma-ray bursts
Elena M. Rossi, Rosalba Perna, Frédéric Daigne
The paucity of reliable achromatic breaks in Gamma-Ray Burst afterglow light curves motivates independent measurements of the jet aperture. Serendipitous searches of afterglows, es…
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…
Dust Echoes from the Ambient Medium of Gamma-Ray Bursts
Kevin Heng, Davide Lazzati, Rosalba Perna
Long gamma-ray bursts (GRBs) are likely associated with the collapse of massive stars, which produce dust and are born in dusty environments. Absorption and scattering of ultraviol…
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…
