DL Tauri
Protoplanetary disk
Star is surrounded by a massive (0.029±0.003 M☉) protoplanetary disk, which is extensive yet relatively flattened and rich in large grains, indicated a significantly evolved state. With a mass this massive the disk can possibly form a brown dwarf. The area of disk about 100 AU from the star may be on the verge of the gravitational instability. The disk have a multiple dust rings with poorly resolved gaps between.
Suspected planetary companion
The object 2MASS J04333960+2520420, designated DL Tau/cc1 in 2008, is a suspected superjovian planet with mass about 12MJ on the likely bound orbit around DL Tauri. The object is either a sub-brown dwarf or a low mass brown dwarf or even a low-mass ultra-cool red dwarf star if strongly veiled by accretion disk, which is not unusual for the young star systems.
