Visual orbit of the low-mass binary GJ 164 AB
We report seven successful observations of the astrometric binary GJ 164 AB system with aperture masking interferometry. The companion, with a near-infrared contrast of 5:1 was detected beyond the formal diffraction limit. Combined with astrometric observations from the literature, these observations fix the parallax of the system, and allow a model-independent mass determination of both components.We find the mass of GJ 164 B to be 0.096±0.008M⊙. With data taken with the newly commissioned...[Show more]
