Breakthrough astrophysicists' model quickly visualizes star collisions

The new breakthrough astrophysics code Octo-Tiger can 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 significantly reducing the computing time,necessary to complete the simulation, we can begin to ask new questions that could not be solved when the simulation of the merger and collision of stars was very time consuming, ”the scientists note.

Test on Australia's fastest supercomputershowed that Octo-Tiger performs excellently 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 for modelingmergers of nearby stars, which 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.
