Abstract:Supernovae are explosions of stars and are a central problem in astrophysics. Rayleigh–Taylor (RT) and Richtmyer–Meshkov (RM) instabilities develop during the star’s explosion and lead to intense interfacial RT/RM mixing of the star materials. We handle the mathematical challenges of the RT/RM problem based on the group theory approach. We directly link the conservation laws governing RT/RM dynamics to the symmetry-based momentum model, derive the model parameters, and find the analytical solutions and charact… Show more
“…The article “Supernova and the Arrow of Time” by Abarzhi et al [ 6 ] examines the Rayleigh–Taylor (RT) and Richtmyer–Meshkov (RM) instabilities developing on very large scales during explosions of stars. This phenomenon involves mixing connecting astrophysical and atomic scales and is strongly time-directional.…”
