V883 Ori, HBC 489
V883 Orionis is a protostar in the constellation of Orion. It is associated with IC 430 (Haro 13A), a peculiar Hα object surveyed by Guillermo Haro in 1952. It is located about 1350 light years (414 parsecs) away, and is associated with the Orion Nebula.
V883 Orionis, like most protostars, is surrounded by a circumstellar disc of dust. The dust has a water snow line, a certain distance where the stellar irradiance from the star is low enough that water can freeze to snow. The water snow line was directly imaged by ALMA, when a stellar outburst increased the amount of insolation and pushed the line out farther.
