Quantum Vacuum Friction in Highly Magnetized Neutron Stars
Arnaud Dupays, Carlo Rizzo, Dimitar Bakalov +1
In this letter we calculate the energy loss of highly magnetized neutron star due to friction with quantum vacuum, namely Quantum Vacuum Friction (QVF). Taking into account one-loo…
Phase-resolved spectroscopy of Geminga shows rotating hot spot(s)
P. A. Caraveo, A. De Luca, S. Mereghetti +2
Isolated neutron stars are seen in x-rays through their nonthermal and/or surface thermal emissions. XMM-Newton observations of the Geminga pulsar show a 43 electron volt spectrum…
XMM-Newton and VLT observations of the isolated neutron star 1E 1207.4-5209
A. De Luca, S. Mereghetti, P. A. Caraveo +3
In August 2002, XMM-Newton devoted two full orbits to the observation of 1E 1207.4-5209, making this isolated neutron star the most deeply scrutinized galactic target of the missio…
Pulse phase variations of the X-ray spectral features in the radio-quiet neutron star 1E 1207-5209
S. Mereghetti, A. De Luca, P. A. Caraveo +3
We present the results of an XMM-Newton observation of the radio-quiet X-ray pulsar 1E 1207-5209 located at the center of the shell-like supernova remnant G296.5+10.0. The X-ray sp…
The distance to the Vela pulsar gauged with HST parallax oservations
P. A. Caraveo, A. De Luca, R. P. Mignani +1
The distance to the Vela pulsar (PSR B0833-45) has been traditionally assumed to be 500 pc. Although affected by a significant uncertainty, this value stuck to both the pulsar and…
Pulsar Counterparts of Gamma-Ray Sources
P. A. Caraveo, G. F. Bignami
The EGRET catalogue of unidentified X-ray sources has more objects along the galactic disk than at high galactic latitude, where identifications are comparatively easier. On the ot…
Is the Fuzziness of GRB970228 constant?
P. A. Caraveo, R. P. Mignani, G. F. Bignami
In view of the data gathered in September 1997, we review the flux values collected so far for the "fuzziness" seen in the optical counterpart of GRB970228. Comparison between the…
