MOA-2011-BLG-262Lb: A SUB-EARTH-MASS MOON ORBITING A GAS GIANT PRIMARY OR A HIGH VELOCITY PLANETARY SYSTEM IN THE GALACTIC BULGE
2014
Abstrakt
We present the first microlensing candidate for a free-floating exoplanet-exomoon system, MOA-2011-BLG-262, with a primary lens mass of Mhost ~ 4 Jupitermasses hosting a sub-Earthmassmoon. The argument for an exomoon hinges on the system being relatively close to the Sun.
