Breakthrough astrophysicists’ model quickly visualizes star collisions

Researchers from the United States a new algorithm that can simulate star collisions faster than any analog. This will accelerate the study of space objects of interest to scientists.

The new breakthrough astrophysical code Octo-Tiger is able to simulate the evolution of self-gravitational and rotating systems. This code for simulating stellar collisions is faster than analogs that are often used for numerical simulations.

“By dramatically reducing the computational time required to complete a simulation, we can start asking new questions that could not be solved when simulating a merger and collision of stars was very time-consuming,” the scientists note.

A test on Australia’s fastest supercomputer showed the Octo-Tiger to perform well for large models of merging and colliding stars. Thus, the algorithm will accelerate the study of stars and other space objects that are of interest to scientists.

So far, Octo-Tiger has been optimized to simulate the merger of nearby stars that can be approximated by barotropic structures such as white dwarfs. The gravity solver preserves angular momentum for accuracy thanks to a correction algorithm. This code uses parallelization, which results in the ability to scale to solve larger problems in shorter periods of time.
