Tolman–Oppenheimer–Volkoff limit

The Tolman–Oppenheimer–Volkoff limit (or TOV limit) is an upper bound to the mass of stars composed of neutron -degenerate matter (i.e. neutron stars ). The TOV limit is analogous to the Chandrasekhar limit for white dwarf stars.

It is approximately 1.5 to 3.0 solar masses, corresponding to an original stellar mass of 15 to 20 solar masses.
