- Description
We present the discovery of a substellar companion to the primary host lens in the microlensing event MOA-2012-BLG-006. The companion-to-host mass ratio is 0.016, corresponding to a companion mass of ≠8 MJup(Mâ-/0.5 MâŠ(tm)). Thus, the companion is either a high-mass giant planet or a low-mass brown dwarf, depending on the mass of the primary Mâ-. The companion signal was separated from the peak of the primary event by a time that was as much as four times longer than the event timescale. W...
