What you should be familiar with
The astrophysical lab deals with the following topics.
If you cannot discuss these subjects to explain the basic physical concepts and their application (including the relevant equations) without looking these up,
you should not take the astrophysical lab until you have brushed up on these topics.
- Parallaxes and distances.
- Magnitudes and colors.
- Hertzsprung-Russell diagram; general properties of stars and their evolution; surface temperatures, masses, sizes.
- Doppler shift, redshift, cosmological distances.
- Error propagation.
- Poissonian and Gaussian statistics.
- Linear regression.
- Hydrogen atom: energy levels and transition wavelengths, Lyman, Balmer, etc. series.
- Basic radiation and radiative transfer concepts: Planck function, Stefan-Boltzmann equation, opacities, emissivities, optical depth.
- Saha-Boltzmann equation.
- General scales and orders of magnitude; sizes of astrophysical objects, their masses and luminosities.
