How to Calculate Chandrasekhar Limit
What is Chandrasekhar Limit?
Chandrasekhar limit (~1.4 solar masses) is maximum mass white dwarf can support against gravitational collapse via electron degeneracy pressure.
Step-by-Step Guide
- 1Input white dwarf mass
- 2Compare to Chandrasekhar limit
- 3Determine stability or collapse fate
Worked Examples
Input
WD mass 1.2 M☉
Result
Below limit, stable
Above limit → neutron star
Common Mistakes to Avoid
- ✕Confusing with Tolman-Oppenheimer-Volkoff limit
- ✕Assuming constant value (varies slightly)
Frequently Asked Questions
What happens above limit?
Electron degeneracy fails; collapse to neutron star or black hole.
