Early evolution of spherical ejecta expanding into the circumstellar matter at ultra-relativistic speeds
arXiv:1202.5833 · doi:10.1093/pasj/64.4.87
Abstract
We present a new self-similar solution describing early evolution of an ultra-relativistic flow resulting from a collision of homologously expanding spherical ejecta with the circumstellar matter, in which a shock wave propagates in the circumstellar matter while a weak discontinuity propagates in the ejecta at the sound speed
