BeppoSAX and Ulysses data on the giant flare from SGR 1900+14
M. Feroci, K. Hurley, R. Duncan +3
The extraordinary giant flare of 1998 August 27 from SGR 1900+14 was the most intense event ever detected from this or any other cosmic source (even more intense than the famous Ma…
High Energy Emission from Magnetars
C. Thompson, A. M. Beloborodov
The recently discovered soft gamma-ray emission from the anomalous X-ray pulsar 1E 1841-045 has a luminosity L_g ~ 10^{36} ergs/s. This luminosity exceeds the spindown power by thr…
The BeppoSAX View on the 2001 Reactivation of SGR 1900+14
M. Feroci, S. Mereghetti, E. Costa +13
After a couple of years of quiescence, the soft gamma repeater SGR 1900+14 suddenly reactivated on 18 April 2001, with the emission of a very intense, long and modulated flare, onl…
Magnetars: Time Evolution, Superfluid Properties, and Mechanism of Magnetic Field Decay
P. Arras, A. Cumming, C. Thompson
We calculate the coupled thermal evolution and magnetic field decay in relativistic model neutron stars threaded by superstrong magnetic fields (B > 10^{15} G). Our main goal is to…
Approaching the dynamics of hot nucleons in supernovae
M. Liebendoerfer, U. -L. Pen, C. Thompson
All recent numerical simulations agree that stars in the main sequence mass range of 9-40 solar masses do not produce a prompt hydrodynamic ejection of the outer layers after core…
Diagnosing magnetars with transient cooling
Y. Lyubarsky, D. Eichler, C. Thompson
Transient X-ray emission, with an approximate t^{-0.7} decay, was observed from SGR 1900+14 over 40 days following the the giant flare of 27 Aug 1998. We calculate in detail the di…
