Self-similar Evolution of Relativistic Shock Waves Emerging from Plane-parallel Atmospheres
TLDR
In this article, the authors studied the evolution of the ultrarelativistic shock wave in a plane-parallel atmosphere adjacent to a vacuum and the subsequent breakout phenomenon and derived the energy spectrum of the ejected matter as a result of the shock breakout.Abstract:
We study the evolution of the ultrarelativistic shock wave in a plane-parallel atmosphere adjacent to a vacuum and the subsequent breakout phenomenon. When the density distribution is a power law in distance from the surface, there is a self-similar motion of the fluid before and after the shock emergence. The time evolution of the Lorentz factor of the shock front is assumed to follow a power law when the time is measured from the moment at which the shock front reaches the surface. The power index is found to be determined by the condition for the flow to extend through a critical point. The energy spectrum of the ejected matter as a result of the shock breakout is derived, and its dependence on the strength of the explosion is also deduced. The results are compared with the self-similar solution for the same problem with nonrelativistic treatment.read more

The afterglow of a relativistic shock breakout and low-luminosity GRBs
TL;DR: In this paper, a general formalism was developed to estimate the afterglow produced by synchrotron emission from the forward shock resulting from the interaction of this ejecta with the circum-burst matter.

Self-similar relativistic blast waves with energy injection
TL;DR: In this article, the effect of limited duration energy injection into environments with density depending on radius is described as a power law, emphasizing optical/X-ray Gamma-ray Burst afterglows as applications.

Oblique shock breakout in supernovae and gamma-ray bursts. I. Dynamics and observational implications
TL;DR: In a non-spherical stellar explosion, non-radial motions become important near the stellar surface as discussed by the authors, where the breakout flash is stifled, ejecta speeds are limited, and matter is cast sideways.

Oblique Shock Breakout in Supernovae and Gamma-Ray Bursts: I. Dynamics and Observational Implications
TL;DR: In this paper, the authors study the shock structure and post-shock acceleration using conservation laws, a similarity analysis, and an approximate theory for oblique shocks, and comment on the implications for several notable explosions in which the non-spherical dynamics described in this paper are likely to play an important role.
