Query: OGLE-2016-BLG-0613LABb: A Microlensing Planet in a Binary System   We present the analysis of OGLE-2016-BLG-0613, for which the lensing light
curve appears to be that of a typical binary-lens event with two caustic spikes
but with a discontinuous feature on the trough between the spikes. We find that
the discontinuous feature was produced by a planetary companion to the binary
lens. We find 4 degenerate triple-lens solution classes, each composed of a
pair of solutions according to the well-known wide/close planetary degeneracy.
One of these solution classes is excluded due to its relatively poor fit. For
the remaining three pairs of solutions, the most-likely primary mass is about
$M_1\sim 0.7\,M_\odot$ while the planet is a super-Jupiter. In all cases the
system lies in the Galactic disk, about half-way toward the Galactic bulge.
However, in one of these three solution classes, the secondary of the binary
system is a low-mass brown dwarf, with relative mass ratios (1 : 0.03 : 0.003),
while in the two others the masses of the binary components are comparable.
These two possibilities can be distinguished in about 2024 when the measured
lens-source relative proper motion will permit separate resolution of the lens
and source.
