Today we have a guest blog from Sasha Hinkley talking about a different way of detecting exoplanets than the transit method we use at Planet Hunters. Sasha is a Sagan Postdoctoral Fellow at the California Institute of Technology in Pasadena, CA. Sasha received his PhD from Columbia University in New York City and has been involved in the direct imaging of exoplanets for several years.
In recent years, astronomers have identified hundreds exoplanets (as well as over 2000 new candidates from the Kepler mission), launching the new and thriving field of exoplanetary science. The vast majority of these objects have been discovered indirectly by observing the variations induced in their host star’s light. The Doppler surveys detect stellar “wobbles” induced by the planets, and provide valuable information about the orbital separations, eccentricities, as ...
