Simultaneous simulation of gravitation and magnetism of a protoplanetary disk

From a massive disk of gas and dust rotating around the sun, the earth and the other seven planets of our solar system once developed alongside their moons. And the same must have happened, scientists believe, for the thousands of extrasolar planets discovered in recent decades. To gain more insight, astrophysicists use computer simulations to investigate the processes at work as planets form from such protoplanetary disks, such as the growth of a planet's mass as well as the formation of its ma...
