Tolman-Oppenheimer-Volkoff Limit

(TOV, LOV, Landau-Oppenheimer-Volkoff Limit)
(maximum mass of a neutron star)

The Tolman-Oppenheimer-Volkoff Limit (TOV or Landau-Oppenheimer-Volkoff Limit or LOV) is the maximum size of a Neutron Star, i.e., the size at which gravitational pull is balanced with the outward Degeneracy pressure. It is the analog of the Chandrasekhar Limit that limits the size of White Dwarves.

It is approximately 1.5 to 3.0 solar masses which is the mass of a neutron star resulting from a star of 15 to 20 solar masses. The limit was seriously theorized by Lev Landau in 1932, worked on by Richard Chace Tolman, and worked out by J. Robert Oppenheimer and George Volkoff in 1939.
