V1094 Scorpii is a young stellar object in the constellation of Scorpius, located in the young Lupus Star Forming Region. [5] It is being orbited by a protoplanetary disk that extends out to a distance of 300 AU from the host star. There are gaps at 100 AU and 170 AU, with bright rings at 130 AU and 220 AU. [4]
Periodic radial velocity variations in the young star V1094 Scorpii had at first been explained by the presence of a substellar object in a tight orbit. [6] Currently, the presence of a substellar object has been retracted, invoking starspots as the actual cause for observed radial velocity variations. [2]
