Between 2008 and 2013, we searched for such planets with the MEarth Project, a photometric survey of the closest and smallest main-sequence stars. This thesis uses the first planet discovered with MEarth, the warm 2.7 Earth radius exoplanet GJ1214b, to explore the possibilities that planets transiting M dwarfs provide.en-USAstronomyAstrophysicsatmospheresexoplanetsM dwarfsphotometrystatisticstransitsThesis or Dissertation2013-10-09
