2MASS J04442713+2512164 (2M0444, IRAS 04414+2506) is a brown dwarf in the Taurus Molecular Cloud. It is surrounded by a protoplanetary disk, which is resolved by multiple observatories. It is one of the brightest brown dwarf disks in millimeter wavelengths.
IRAS 04414+2506 was first identified as a good pre-main sequence star with IRAS in 1994, resembling a class II disk. In 2004 it was identified as the 2MASS source J04442713+2512164 and identified as a brown dwarf as part of the Taurus Cloud for the first time by Kevin Luhman.
