Zusammenfassung: | We present experiments to reproduce the characteristics of core-collapse
supernovae with different stellar masses and initial explosion energies in the
laboratory. In the experiments, shocks are driven in 1.2 atm and 1.9 atm xenon
gas by laser with energy from 1600J to 2800J on the SGIII prototype laser
facility. The average shock velocities and shocked densities are obtained from
experiments. Experimental results reveal that higher laser energy and lower Xe
gas density led to higher shock velocity, and lower Xe gas initial density has
a higher compression. Modeling of the experiments using the 2D radiation
hydrodynamic codes Icefire shows excellent agreement with the experimental
results and gives the temperature. These results will contribute to time-domain
astrophysical systems, such as gravitational supernovae, where a strong
radiative shock propagates outward from the center of the star after the core
collapses. |
