The neutrinos, born in the collapsing core, drain energy from the shock wave. The shock stalls, and-- at least in the computer--the supernova is a dud. Now Burrows and his colleagues are working with a computer model powerful enough to simulate how the core shakes and churns during the collapse, and they've finally seen how a collapsing star could turn around and explode. The turbulent infalling gas starts shaking the core, causing it to pulsate. Raining down from the star's outer layers, the gas wraps around the core, dancing over its surface and penetrating its depths. "The core is oscillating, and the stuff falling onto the core is exciting it," says Burrows. In about eight-tenths of a second, the oscillations are so intense they send out sound waves. The waves exert a pressure that expels material, reinforcing the shock wave created by the star's collapse.
