Magnetic fields found in a jet from a baby star
An international research team led by Chin-Fei Lee in the Academia Sinica Institute of Astronomy and Astrophysics (ASIAA) has made a breakthrough observation with the Atacama Large Millimeter/submillimeter Array (ALMA), confirming the presence of magnetic fields in a jet from a protostar. Jets are believed to play an important role in star formation, enabling the protostar to accrete mass from an accretion disk by removing angular momentum from the disk. It is highly supersonic and collimated, and predicted in theory to be launched and collimated by magnetic fields. The finding supports the theoretical prediction and confirms the role of the jet in star formation.
