Hunting for Extrasolar Planets: Methods and Results
... A photometric method: Transits. This is the most active area of planet searching today because 1. It does not require a large telescope! 2. Chances of finding a planet-star system nearly edge-on is small, so need lots of observations; 3. Big payoff: you can learn about a stars diameter and mass, an ...
