Radius (R_sun) vs White Dwarf Mass
सूत्र
## White Dwarf Mass-Radius Relation White dwarfs are supported by electron degeneracy pressure. An unusual property: more massive white dwarfs are smaller. ### Approximate Relation **R / R_sun ≈ 0.0126 × (M/M_sun)^(-1/3)** A 0.6 M_sun white dwarf is roughly Earth-sized. As mass approaches the Chandrasekhar limit (1.4 M_sun), the radius shrinks toward zero.
हल किया गया उदाहरण
A 0.6 M_sun white dwarf.
- 01R/R_sun = 0.0126 × 0.6^(-1/3)
- 020.6^(-1/3) = 1/(0.6^(1/3)) = 1/0.8434 = 1.1856
- 03R/R_sun = 0.0126 × 1.1856 = 0.01494
- 04R = 0.01494 × 695700 = 10 394 km ≈ 1.63 R_Earth
अक्सर पूछे जाने वाले प्रश्न
Why are heavier white dwarfs smaller?
More mass means stronger gravity, compressing the degenerate electron gas further. This is the opposite of normal stars.
What is a typical white dwarf mass?
About 0.6 M_sun. Most white dwarfs fall between 0.5 and 0.8 M_sun.
How dense is a white dwarf?
About 10^6 kg/m³ on average (a million times water). A teaspoon would weigh about a tonne.
