DL Tauri is a young T Tauri-type pre-main sequence stars in the constellation of Taurus about 522 light years away, belonging to the Taurus Molecular Cloud. It is partially obscured by the foreground gas cloud rich in carbon monoxide,[4] and is still accreting mass, producing 0.14 L☉ due to release of accretion energy.[3] The stellar spectrum shows the lines of ionized oxygen, nitrogen, sulfur and iron.[3]
