What is the Tolman-Oppenheimer-Volkoff limit? The Tolman-Oppenheimer-Volkoff limit is the maximum mass a neutron star can have before collapsing into a black hole. This limit, named after physicists Richard Tolman, J. Robert Oppenheimer, and George Volkoff, is crucial in astrophysics. It helps scientists understand the life cycle of stars and the formation of black holes. Neutron stars, which are incredibly dense remnants of supernova explosions, can only support so much mass before gravity wins, causing them to collapse. The exact value of this limit isn't fixed but is generally estimated to be between 2 to 3 times the mass of our Sun. Understanding this limit helps us grasp the extreme conditions in the universe and the fate of massive stars.
What is the Tolman-Oppenheimer-Volkoff Limit?
The Tolman-Oppenheimer-Volkoff (TOV) limit is a critical concept in astrophysics. It defines the maximum mass a neutron star can have before collapsing into a black hole. This limit is named after physicists Richard Tolman, J. Robert Oppenheimer, and George Volkoff, who developed the theory in the 1930s.
- The TOV limit is estimated to be between 2.1 and 2.3 solar masses.
- Neutron stars exceeding this mass cannot support themselves against gravitational collapse.
- The exact value of the TOV limit is still uncertain due to complexities in neutron star matter.
