The simulation shown here marks the birth of a magnetic star such as Tau Scorpii. The movie shows cuts through the orbital plane where the colouring indicates the strength of the magnetic field and the hatching represents its field lines.
A scientific study about this simulation is published in the 10th October 2019 issue of Nature and can be found here: https://www.nature.com/articles/s41586-019-1621-5
