We compare potential state-of-the-art experiments for detecting Earth-mass planets around main-sequence stars using radial velocities, transits, astrometry, and microlensing. For conventionally-discussed signal-to-noise ratio (S/N) thresholds, S/N ~ 8, the last three methods are roughly comparable in terms of both the total number of planets detected and the mass distribution of their host stars. However we argue that S/N ~ 25 is a more conservative and realistic S/N threshold. We show… 
Detecting New Planets in Transiting Systems
I present an initial investigation into a new planet detection technique that uses the transit timing of a known, transiting planet. The transits of a solitary planet orbiting a star occur at equally
The First Planetary Microlensing Event with Two Microlensed Source Stars
We present the analysis of the microlensing event MOA-2010-BLG-117, and show that the light curve can only be explained by the gravitational lensing of a binary source star system by a star with a
The Microlensing Planet Finder: completing the census of extrasolar planets in the Milky Way
The Microlensing Planet Finder (MPF) is a proposed Discovery mission that will complete the first census of extrasolar planets with sensitivity to planets like those in our own solar system. MPF will
Community Involvement in the WFIRST Exoplanet Microlensing Survey.
TLDR
A set of high level data products are proposed that will enable astronomers without detailed microlensing expertise access to the statistical implications of the WFIRST exoplanetmicrolensing survey data and the formation of a WFIRst Exoplanet Microlensing Community Science Team is proposed.
