A point explosion in a freely expanding medium
Received 14 August 1997 / Accepted 16 March 1998
We present an exact invariant solution for a point explosion in an inertially expanding medium. The blast wave dynamics continuously joins the self-similar Sedov asymptotics at early times and asymptotical comoving with the ambient medium at late times. The applications to galactic supershell blowout dynamics and cosmological explosions are discussed.
