The Benchmark Ultracool Subdwarf HD 114762B: A Test of Low-Metallicity Atmospheric and Evolutionary Models
HD 114762A is a low-metallicity star that was discovered to have a massive substellar companion (probably a brown dwarf) in 1989, which has at least 11 Jupiter masses. The secondary star HD 114762B has spectral type d/sdM9, a "mild subdwarf".

Mass is 88 Jupiter masses, so it's likely a very low mass STAR, with Jupiter-sized radius though. Hydrogen-deuterium limit is placed (though a bit arbitrarily according to some authors) above 78-80 Jupiter masses (i.e 0.077-0.08 Solar masses).
