We present an updated analysis of LHS 6343, a triple system in the Keplerfield which consists of a brown dwarf transiting one member of awidely-separated M+M binary system. By analyzing the full Kepler dataset and 34Keck/HIRES radial velocity observations, we measure both the observed transitdepth and Doppler semiamplitude to 0.5% precision. With Robo-AO andPalomar/PHARO adaptive optics imaging as well as TripleSpec spectroscopy, wemeasure a model-dependent mass for LHS 6343 C of 62.1 +/- 1.2 M_Jup and aradius of 0.783 +/- 0.011 R_Jup. We detect the secondary eclipse in the Keplerdata at 3.5 sigma, measuring e cos omega = 0.0228 +/- 0.0008. We also derive amethod to measure the mass and radius of a star and transiting companiondirectly, without any reliance on stellar models. The mass and radius of bothobjects depend only on the orbital period, stellar density, reduced semimajoraxis, Doppler semiamplitude, eccentricity, and inclination, as well as theknowledge that the primary star falls on the main sequence. With this method,we calculate a model-independent mass and radius for LHS 6343 C to a precisionof 3% and 2%, respectively.
