Powerful Magnetic Fields Allow Dead Stars to Break Physics’ Famous Chandrasekhar Limit
New simulations suggest intense internal magnetic fields may allow white dwarfs to reach about 2.4 solar masses, far above the traditional 1.4-solar-mass Chandrasekhar limit. Modeling shows magnetic pressure can resist gravitational collapse as a white dwarf gains material, potentially explaining unusually bright Type Ia supernovae, oversized low-mass white dwarfs, and improving cosmic distance measurements.
