HOPS 383 is a Class 0 protostar. It is the first class-0 protostar discovered to have had an outburst,[1] and as of 2020, the youngest protostar known to have had an outburst.[1] The protostar was discovered by the Herschel Orion Protostar Survey (HOPS) team.[2]
Outburst
HOPS 383 had an outburst between 2004 and 2006 (a "dramatic mid-infrared brightening"); the increase in magnitude was detectable at the 24 μm (35 times) and 4.5 μm, and was also detectable at the submillimetre.[3] After 6 years, observations showed no signs of fading.[3]
