  • How do we know that exoplanets exist? How many are there?
  • Describe two methods of detecting exoplanets
  • If an exoplanet transits a star, how does the luminosity change? Draw an plot of L vs t to scale
  • What discovery ~15 years ago made exoplanet searches feasible? (The question was phrased pretty strangely. Hint: What "class" of exoplanets were discovered about then?)
  • What is the probability of finding an eclipsing system?
