... If all stars (in some mass range) have on average 2 planets with R = Rearth orbiting between 0.5 au and 1.5 au, ~50 will be detected. Likely to provide first clue as to how common habitable planets are. Possible that gravitational lensing (even less direct method, discussed next semester) will find ...

finding masses of extrasolar planets
... Each of the various techniques for finding extrasolar planets also provides extra information about the planets and their stars. For example, the Doppler technique gives us information about the star’s velocity toward or away from us, and from this we can find it’s mass. It is possible to calculate ...
