Two-color microlensing observations and the abundance of Earth-mass planets

Markus Hundertmark , ARI

Galactic gravitational microlensing events offer the unique opportunity to discover sub-Neptune mass planets orbiting stars located several kiloparsecs away from Earth. Moreover, the orbital radius is likely to be outside the snow line of water ice. Since the first reported microlensing planet in 2003, more than 50 exoplanets have been found with this method. Determining the planet mass and its orbital radius remains a challenge and often requires follow-up observations and further constraints. In this talk, I present new results of the RoboNet follow-up team and provide an outlook on how our recently approved LCO (Las Cumbres Observatory) key project will address the issue of determining the abundance of planets in the next three years.
