Abstract (from CDS):

We report the detection of a substellar companion orbiting the G5 dwarf HD 16760 from the N2K sample. Precise Doppler measurements of the star from Subaru and Keck revealed a Keplerian velocity variation with a period of 466.47±0.35 d, a semiamplitude of 407.71±0.84 m/s, and an eccentricity of 0.084±0.003. Adopting a stellar mass of 0.78±0.05 M, we obtain a minimum mass for the companion of 13.13±0.56 MJUP, which is close to the planet/brown-dwarf transition, and the semimajor axis of 1.084±0.023 AU. The nearly circular orbit despite the large mass and intermediate orbital period makes this companion unique among known substellar companions.
