Target entity: Chandrasekhar limit
Context triple: [Subrahmanyan Chandrasekhar, knownFor, Chandrasekhar limit]
  • A. Schwarzschild radius
    The Schwarzschild radius is the critical distance from the center of a non-rotating, spherically symmetric mass at which its escape velocity equals the speed of light, defining the boundary of a black hole.
  • B. Chandrasekhar–Friedman–Schutz instability
    The Chandrasekhar–Friedman–Schutz instability is a gravitational-radiation-driven instability in rotating stars that can cause certain oscillation modes to grow by emitting gravitational waves.
  • C. Oppenheimer–Snyder model
    The Oppenheimer–Snyder model is a pioneering theoretical description of gravitational collapse in general relativity, providing one of the first rigorous treatments of how a massive star can form a black hole.
  • D. Chandrasekhar number
    The Chandrasekhar number is a dimensionless quantity in magnetohydrodynamics that measures the relative importance of magnetic forces compared to viscous forces in a conducting fluid.
  • E. Subrahmanyan Chandrasekhar
    Subrahmanyan Chandrasekhar was an Indian-American astrophysicist and Nobel laureate renowned for his work on stellar structure and evolution, particularly the Chandrasekhar limit for white dwarfs.
  • F. None of above. chosen
  • G. Unsure - the case is ambiguous/there is not enough information to decide.
