Average Density vs Neutron Star Mass
公式
## Neutron Star Density ### Formula **rho = 3M / (4π r³)** A typical neutron star (1.4 M_sun, 10 km radius) has an average density near nuclear density (~2.3 × 10¹⁷ kg/m³). A sugar-cube-sized chunk would weigh about a billion tonnes.
计算示例
A 1.4 M_sun neutron star with r = 10 km.
- 01rho = 3M / (4π r³)
- 024π r³ = 4π × (10000)³ = 1.257e13 m³
- 03rho = 3 × 2.78e30 / 1.257e13 = 6.63e17 kg/m³
- 04About 2.9 times nuclear density.
常见问题
What is nuclear density?
About 2.3 × 10¹⁷ kg/m³, the density of an atomic nucleus. Neutron stars are comparable to giant atomic nuclei.
How massive can a neutron star be?
The Tolman-Oppenheimer-Volkoff limit is roughly 2-3 solar masses. Above this, collapse to a black hole is inevitable.
What is a teaspoon of neutron star material?
About 5 ml × ~5e17 kg/m³ = ~2.5 billion tonnes. It would weigh more than Mount Everest.
