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.[2] In 2023, it was announced that signs of water vapor had been detected in V883 Orionis' disc.[5]
