DL Tauri is a young T Tauri-type pre-main sequence stars in the constellation of Taurus about Шаблон:Val away, belonging to the Taurus Molecular Cloud. It is partially obscured by the foreground gas cloud rich in carbon monoxide,[1] and is still accreting mass, producing 0.14 Шаблон:Solar luminosity due to release of accretion energy.[2] The stellar spectrum shows the lines of ionized oxygen, nitrogen, sulfur and iron.[2]

Protoplanetary disk

Star is surrounded by a massive (0.029Шаблон:± Шаблон:Solar mass) protoplanetary disk,[3] 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.[3] The disk have a multiple dust rings with poorly resolved gaps between.[4]

Suspected planetary companion

The object 2MASS J04333960+2520420, designated DL Tau/cc1 in 2008, is a suspected superjovian planet with mass about 12Шаблон:Jupiter mass 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.[5]
