This isn't really a hot Jupiter. At around 13 Jupiter masses, an object is capable of deuterium fusion and is thus a star, though a failed star known as a brown dwarf. At 75 Jupiter masses, regular fusion of hydrogen becomes possible and an object is a small regular star, specifically a red dwarf. This object is 80 Jupiter masses. There are some complicating factors so whether this is actually a red dwarf or a brown dwarf is not clear, but it's definitely a very different beast than a Jupiter sized planet.
