Neutron Stars in Supernovae and Their Remnants
Roger A. Chevalier
- 23 Sep 2011
TL;DR: The magnetic fields of neutron stars have a large range and are typically dominated by other power sources in supernovae as discussed by the authors, which may explain the tendency for more highly magnetized neutron stars to come from more massive stellar progenitors.

Theoretical Implications of the Gamma-Ray Burst - Supernova Connection
TL;DR: In this article, the authors show that a 1/r**2 density profile wind surrounding the progenitor star surrounding the gamma-ray burst (GRB) afterglows is consistent with wind interaction if the injection particle spectrum is a broken power law.

Shock Breakout in Dense Mass Loss: Luminous Supernovae
TL;DR: In this article, the authors examined the case where a circumstellar medium around a supernova is sufficiently opaque that a radiation dominated shock propagates in the circumstellar region, and argued that SN 2006gy is an example of the first kind of event, while SN 2010gx and related supernovae are examples of the second.

- 22 May 2008
TL;DR: In this paper, a comprehensive multi-wavelength analysis of the gamma-ray burst GRB 070125 is presented, consisting of observations in gamma ray, X-ray, optical, millimeter and centimeter wavebands.
Interaction of Supernova Eject with Interstellar and Circumstellar Matter
E. P. Liang,Roger A. Chevalier +1 more
TL;DR: In this paper, a series of one-dimensional numerical simulations of supernova ejecta interactions with both interstellar and circumstellar matter whose results are presented was prompted by Chevalier's (1982) indication that the late time behavior of such interactions can be modeled by certain exact analytic self-similar solutions corresponding to ideal gas spheres whose profiles expand into a rarefied ambient medium.
