DH Tauri

DH Tauri, also known as DH Tau, is a type M star, located 140 parsecs (456.619 light years) away. It forms a binary system with DI Tauri 15" away, and has a substellar companion, either a brown dwarf or massive exoplanet. DH Tauri is a type M, or red dwarf star, one of the most common types of star in the Milky Way. It has an apparent magnitude of 13.71, so it's not visible from Earth using the naked eye and has a temperature of 3751K. DH Tauri has a mass of and an estimated radius of . The companion DH Tauri B or b has a mass estimated to be between and , making it either a super-Jupiter or brown dwarf. Other sources give a mass as high as , with a bolometric luminosity of . The spectral type has been classified as M7.5 or M9.25. 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).
