DH Tauri is a type M, or red dwarf star, one of the most common types of star in the Milky Way.[6] It has an apparent magnitude of 13.71 and temperature of 3,751 K. DH Tauri has a mass of 0.41 M☉ and an estimated radius of 1.26 R☉.
The companion DH Tauri B or b has a mass estimated to be between eightMJ and 50MJ, making it either a super-Jupiter or brown dwarf.[7][8] Other sources give a mass as high as 0.03 M☉, with a bolometric luminosity of 0.01 L☉.[9] The spectral type has been classified as M7.5[9] or M9.25.[10] The companion, while its host star still having a protoplanetary disk, is still accreting material, being surrounded by a circumsubstellar disk (possibly a circumplanetary disk, depending on its formation history).[11]
