What object results if the initial collapsing mass is too low to start hydrogen fusion?

Answer

Brown dwarf

If the initial mass is below about 0.08 times the mass of the Sun, the core never achieves the temperature necessary for hydrogen fusion, and the object becomes a brown dwarf, shining only from residual heat.
