  • Precision Doppler velocity measurements from the Anglo-Australian Telescope reveal a planet with a 9.4 ± 0.4 year period orbiting the M1.5 dwarf GJ 832. Within measurement uncertainty the orbit is circular, and the minimum mass (msin i) of the planet is 0.64 ± 0.06 M JUP. GJ 832 appears to be depleted in metals by at least 50% relative to the Sun, as are a significant fraction of the M dwarfs known to host exoplanets. GJ 832 adds another Jupiter-mass planet to the known census of M dwarf… CONTINUE READING
