- Describe the current effort to detect planets orbiting stars other than our sun. (JW)
- 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?
- How many transiting exoplanets have been detected from space. How many have been detected from the ground?
- Calculate the temperature of an exoplanet caused by reflection of the parent star's light. (SR)
- What information may be obtained if two transits of an exoplanet are observed? More than two? (RS)
- At what radii are transits most common, smaller or larger than a Mercury orbit? What is the distance to Mercury's orbit?
- Derive the probability of seeing a transit. (AB)
- Given a planet of temperature T, and a Sun-like star, derive the distance from star? (AB)
- What transit depth would you see from a Jupiter sized object passing in front of a Sun-like star?
- What are the effects that could cause the absorption line of a star to be broadened? (JW)
- About how long will it take the Kepler telescope to confirm its first Earthlike planet? (PJ)
- What is Kepler?
- What is the habitable zone? How does the temperature scale with luminosity and distance?
- Might a Jupiter or bigger sized planet in the habitable zone harbor life? What about its moons?
- What is the M Dwarf opportunity? What do M Dwarfs make easier for transit searches? For RV searches? What are the drawbacks?
