Florida State University (FSU) computational scientist Tomasz Plewa and colleagues have demonstrated the conditions underlying the explosion of Type Ia supernovae through refined computational analysis. Earlier studies proposed that flames existed within the star from the onset of detonation, but Plewa’s study did not assume this, accounting only for turbulence and nuclear burning. The FSU team’s computer calculations showed that the flame could occur naturally and spread over time due to the self-heated, sustained turbulence. The turbulence produces an environment where the flame can be efficiently accelerated, inevitably leading to an explosion. Said Plewa, «The time here is measured in milliseconds. It all happens very, very quickly.»
