X-ray Observations of an Outbursting Class 0 Protostar in Orion
Abstract
Class 0 protostars are the earliest observed stage of stellar evolution, where a hydrostatically supported protostar is rapidly accreting mass from a massive infalling envelope. This accretion is thought to be mediated by a disk, potentially via the magnetic field of the central protostar. Evidence for stellar magnetic fields around Class 0 protostars, however, is limited. Searches for X-ray emission from Class 0 protostars have produced only one reliable detection: the post-outburst protostar HOPS 383. We propose observations of HOPS 124, the most luminous of the three known currently or recently outbursting Class 0 protostars. Since the outburst may subside in the near future, this object provides a rare opportunity. These data will complement JWST searches for magnetospheric accretion.
