Computer Simulation of the Re-ignition of a Burnt Out Star Posted on YouTube Mar 6, 2014

For an explanation, pair with this post on Sakurai’s Object.

This is a simulation of the helium shell flash convection and subsequent hydrogen ingestion that took place in the post-AGB star Sakurai's object. This simulation was run on the Bluewaters system at NCSA in 2013 and 2014 on over 400,000 CPU cores.
