Description

We report the discovery, via the microlensing method, of a new very-low-mass binary system. By combining measurements from Earth and from the Spitzer telescope in Earth-trailing orbit, we are able to measure the microlensing parallax of the event, and find that the lens likely consists of an (12.0 \pm 0.6) M3 + (15.7 \pm 1.5) M3 super-Jupiter / brown-dwarf pair. The binary is located at a distance of (3.08 \pm 0.18) kpc in the Galactic Plane, and the components have a projected separation of ...
