TL;DR: A "second-generation" microlensing survey for extrasolar planets, consisting of near-continuous time coverage by the OGLE, MOA, and Wise surveys, suggests a minimum in the distribution in the super-Jupiter mass range, and a relatively high occurrence of brown-dwarf companions.
Journal ArticleDOI

TL;DR: In this article, the authors used a 61 cm telescope located in New Zealand to search for transit timing variations (TTVs), which can be induced by additional bodies existing in the system.

TL;DR: In this article, the authors presented the discovery via gravitational microlensing of two very low mass, very tight binary systems, which have directly and precisely measured total system masses of 0.025 M and 0.034 M, respectively, making them the lowest mass and tightest field brown dwarfs known.

TL;DR: In this article, the optical counterpart of the gamma-ray burst GRB 990712 was observed in the V, R, and I bands during the first ~35 days after the outburst and the observed light curves were fitted with a power-law decay for the optical transient (OT), plus an additional component that was treated in two different ways.

TL;DR: In this article, microlensing parallax observations of OGLE-2015-BLG-1212 decisively break a degeneracy between planetary and binary solutions that is somewhat ambiguous when only ground-based data are considered.
