HOPS 383
HOPS 383 is a Class 0 protostar. It is the first class-0 protostar discovered to have had an outburst,[1] and as of 2015, the youngest protostar known to have had an outburst.[1] The protostar was discovered by the Herschel Orion Protostar Survey (HOPS) team.[2]
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.
