What I do

• Analyze stellar structure and evolution
• Model galactic dynamics and dark matter
• Calculate orbital mechanics for spacecraft
• Simulate gravitational lensing
• Predict cosmic microwave background anisotropies
• Study exoplanet detection methods

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
