Astronomy Test 1

  1. Distance Modulus
  2. Luminosity
    Energy per time
  3. Flux
    • Apparent brightness
    • Luminostiy per unit area
    • Energy per unit time per unit area
  4. Equation for Flux
  5. Apparent magnetudes
  6. Absolute magnetudes
  7. Bolometric Magnetude
  8. Temperature approximation using color index
  9. Radii of stars
  10. Luminosity and Temperature
  11. Masses
  12. Radii, Luminosities, and Temperatures
  13. Types of Bianaries
    • Apparent
    • Visual
    • Spectroscopic
    • Eclipsing
    • Astronomic
  14. Hydrostatic Equilibrium
  15. Opacity
  16. Mean Free Path
  17. HR Diagram axis

  28. Boltzmann's Equation
    • Ratio increases as T goes to infinity
  29. Mass Function
  30. Wien's Law
  31. Population I stars
    • Young
    • High metal content
    • Formed from dead stars
    • All O and B are PopI
  32. Population II stars
    • Old
    • Low Metal content
    • First stars to form
    • Low mass
