Скачать или смотреть Three-Dimensional Core-Collapse Supernova (highest resolution)

This movie shows the time-evolution of the shock wave that is created when the core of a massive star collapses to a proto-neutron star. The shock does not immediately explode the star but "stalls" (because the outer parts of the star [not shown in the movie] are excerting ram pressure on it). The shock is "revived" within a tenth of a second or so, most likely, by heating by neutrinos emitted from the proto-neutron star. The different colors correspond to gas of different temperature (the variable shown is "specific entropy", which is closely related to temperature). Blue corresponds to the coldest gas, green is hotter gas, and yellow and red are the hottest gas.

The box-like features visible at the beginning of the movie are an artifact of the simulation method that was used. They appear when the newborn shock crosses a grid boundary of the computational grid.
