Dynamics and Radiation of Young Type-Ia Supernova Remnants: Important Physical Processes
Lundqvist, P.; Sorokina, E. I.; Blinnikov, S. I. +1 more
We analyze the physical processes that should be taken into account when modeling young type-Ia supernova remnants (SNRs) with ages of several hundred years in which forward (into the interstellar medium) and reverse (into the ejection) shocks propagate. We show that the energy losses in a heavy-element-rich ejection can be significant for SNRs ev…
Broadband Observations of the Transient X-ray Pulsar SAX J2103.5+4545
Sunyaev, R. A.; Lutovinov, A. A.; Revnivtsev, M. G. +5 more
We investigated the optical, X-ray, and gamma-ray variability of the pulsar SAX J2103.5+4545. Our timing and spectral analyses of the X-ray and gamma-ray emissions from the source using RXTE and INTEGRAL data show that the shape of its spectrum in the energy range 3-100 keV is virtually independent of its intensity and the orbital phase. Based on …
