Transiting Planets with LSST I: Potential for LSST Exoplanet Detection

The Large Synoptic Survey Telescope (LSST) has been designed in order to satisfy several different scientific objectives that can be addressed by a ten-year synoptic sky survey. However, LSST will also provide a large amount of data that can then be exploited for additional science beyond its primary goals. We demonstrate the potential of using LSST data to search for transiting exoplanets, and in particular to find planets orbiting host stars that are members of stellar populations that have been less thoroughly probed by current exoplanet surveys. We find that existing algorithms can detect in simulated LSST light curves the transits of Hot Jupiters around solar-type stars, Hot Neptunes around K dwarfs, and planets orbiting stars in the Large Magellanic Cloud. We also show that LSST would have the sensitivity to potentially detect Super-Earths orbiting red dwarfs, including those in habitable zone orbits, if they are present in some fields that LSST will observe. From these results, we make the case that LSST has the ability to provide a valuable contribution to exoplanet science.
