2 CHARACTERIZING SMALL PLANETS WITH K2 AND HARPS-N FOLLOW-UP STUDIES OF THE SMALL PLANETS DETECTED BY KEPLER HAVE REVEALED A REMARKABLE DIVERSITY OF PLANET DENSITIES, INDICATING THAT PREDICTING PLANETARY PROPERTIES FROM A RADIUS MEASUREMENT ALONE COULD LEAD TO SIGNIFICANT ERRORS IN OUR ESTIMATE OF THE FREQUENCY OF ROCKY (AND POSSIBLY HABITABLE) WORLDS. WE PROPOSE TO STUDY THE RELATIONSHIP BETWEEN THE MASSES, RADII, INSOLATION, AND METALLICITIES OF SMALL PLANETS BY TARGETING MODERATELY BRIGHT STARS WITH K2 AND CONDUCTING FOLLOW-UP HIGH-PRECISION RADIAL VELOCITY (RV) MEASUREMENTS WITH HARPS-N. OUR GOAL IS TO OBTAIN A MASS PRECISION OF 15%, THE MINIMUM VALUE REQUIRED TO DISTINGUISH BETWEEN COMPOSITIONAL MODELS. THIS PROJECT REQUIRES NEW K2 DATA FOR TWO REASONS. FIRST, MOST TRANSITING SMALL PLANETS DETECTED BY KEPLER ORBIT STARS TOO FAINT FOR RV OBSERVATIONS, AND SOME OF THE BRIGHT KEPLER HOST STARS ARE NOT AMENABLE TO RV OBSERVATIONS BECAUSE OF THE VARIABILITY OF THE HOST STAR OR THE PRESENCE OF NEARBY STARS. SECOND, THE ANTICIPATED NUMBER OF SMALL PLANETS ORBITING QUIET, BRIGHT STARS DETECTED IN K2 CAMPAIGNS TO DATE (FIELDS 0-7) IS SMALL. WE PROPOSE A RANKED LIST OF 8023 FGKM DWARF STARS THAT ARE BRIGHT ENOUGH FOR RV FOLLOW-UP AND FAINT ENOUGH THAT THEY WILL NOT REQUIRE UNREASONABLY LARGE K2 TARGET APERTURES.
