Visualization of gas flows around a binary protostar system calculated by ATERUI III. The gas shown in red orbits around one of the two protostars. The gas shown in blue orbits around the combined binary system. The gas shown in green is being expelled from the system and is carrying away angular momentum. The present research shows that the magnetic field plays an important role in expelling gas and angular momentum. Credit: Matsumoto, Hotokezaka, Inayoshi 2026 Many stars are born inside vast
