Scientists have found a novel way to make three-dimensional computer simulations of supernovae explosions that may help in understanding these explosions better.
A Princeton-led team used powerful supercomputers to employ a representation in three dimensions that allowed the various multidimensional instabilities to be expressed.
Even though these mammoth explosions have been observed for thousands of years, for the past 50 years researchers have struggled to mimic the step-by-step destructive action on computers. Lead researcher Adam Burrows and his colleagues came up with mathematical values representing the energetic behaviors of stars by using partial differential equations—mathematical representations of fluids in motion. To solve these complex equations and simulate what happens inside a dying star, the team used an advanced computer code that took into account factors that changed over time, including fluid density, temperature, pressure, gravitational acceleration and velocity.
