Lecture 36: Exoplanets - Planets Around Other Stars


Listen Later

Are there planets around other stars? This lecture reviews the methods
used to hunt for exoplanets and the results thus far. I will describe
direct imaging methods, indirect methods relying on the gravitational
influence of the planet on its parent star, planetary transits in which
a planet blocks part of its parent star's light, and gravitational
microlensing. There has been an explosion in our knowledge of planets
around other stars, from little or nothing in the early 1990s to more
than 400 planets around some 340-odd stars as of today. Recorded live
on 2009 Nov 17 in Room 1005 Smith Laboratory on the Columbus campus of
The Ohio State University.
