Abstract

Laboratory simulation of the ejecta-ring collision of Supernova 1987A has been performed by using a high power laser syste. Pure hydrodynamic modeling was applied using the invariance of the Euler equations and the experiment was designed with 1D hydrodynamic simulations. Three laser beams of (lambda) equals 0.53 micrometers , at the intensity I equals 2 X 10¹⁴ W/cm² irradiated a CH foil to generate a strong shock wave and subsequent dense plasma flow in a low density CHO foam including a solid sphere at its center. Shock wave propagation and ma sam flow with vortex ring-like structures were observed with gated x-ray radiography. Overall hydrodynamic behaviors are consistent with 1D and 2D hydrodynamic simulations. The collision dynamics is dominated by a complicated interplay of reflected shock, diffracted shock, transmitted shock waves, and plasma flow behind the main shock passage.
