When to use me
When analyzing astronomical observations, designing space missions, or modeling cosmic phenomena.
Key Concepts
- Stellar Evolution: Main sequence → red giant → white dwarf/neutron star/black hole
- HR Diagram: Luminosity vs temperature relationship for stars
- Schwarzschild Radius: r_s = 2GM/c² defines black hole event horizon
- Virial Theorem: 2K + U = 0 for gravitationally bound systems
- Kepler's Laws: Orbital periods and distances for planetary systems
- Mass-Luminosity Relation: L ∝ M^3.5 for main sequence stars
