MOA-2013-BLG-220Lb: MASSIVE PLANETARY COMPANION TO GALACTIC-DISK HOST Academic Article uri icon

abstract

  • We report the discovery of MOA-2013-BLG-220Lb, which has a super-Jupiter mass ratio q = 3.01 0.02 10 -3 relative to its host. The proper motion, = 12.5 1 mas yr -1 , is one of the highest for microlensing planets yet discovered, implying that it will be possible to separately resolve the host within 7 yr. Two separate lines of evidence imply that the planet and host are in the Galactic disk. The planet could have been detected and characterized purely with follow-up data, which has important implications for microlensing surveys, both current and into the Large Synoptic Survey Telescope (LSST) era. 2014.
