The more mass the star has the more pressure it has to create heat . When it has the right pressure and heat to fuse hydrogen it will start a nuclear fusion and a main sequence star. A brown dwarf does not have enough mass to fuse its fuel. However, it's mass, pressure in it's core is extremely hot but not enough to start a nuclear fusion. The red dwarf is a main sequence star and it burns its fusion at a very slow rate for 100 billion years. The more mass the star is the more it uses up it nuclear fuel, the less mass the star has the less it uses its nuclear fuel

Neil's wrong as he so often is.

Quick Googling indicates we'd 13.8 Jupiter masses to fuse deuterium which would make a brown dwarf. And 80 Jupiter masses to make a red dwarf.
