HOPS 383

Infrared images from instruments at Kitt Peak National Observatory (left) and NASA's Spitzer Space Telescope document the outburst of HOPS 383, a young protostar in the Orion star-formation complex. The background is a wide view of the region taken from a Spitzer four-color infrared mosaic.

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]

Observations

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 increase) and 4.5 μm, and was also detectable at the submillimetre.[3] After 6 years, observations showed no signs of fading.[3]

X-Ray

The Chandra X-Ray Observatory detected an X-ray flare from HOPS 383 in December of 2017.[4] This was the first detection of X-rays from a Class 0 protostar that will evolve into a sun-like star.[4] The flare lasted 3 hours and 20 minutes.[5] It significantly impacted the previously-thought timeline for when such events occur in the evolution of a protostar. Furthermore, it has improved astronomers' understanding of the Sun's earlier evolutionary stages.
