英文摘要	We report the discovery of a substellar companion around the intermediate-mass giant HD 175679. Precise radial velocity data of the star from the Xing long Station and the Okayama Astrophysical Observatory revealed a Keplerian velocity variation with an orbital period of 1366.8+/-5.7 d, a semiamplitude of 380.2+/-3.2 m s(-1) and an eccentricity of 0.378 +/- 0.008. Adopting a stellar mass of 2.7 +/- 0.3 M-circle dot, we obtain that the minimum mass of the HD 175679 b is 37.3+/-2.8 M-J and the semimajor axis is 3.36+/-0.12 AU. This discovery is the second brown dwarf companion candidate from a joint planet-search program between China and Japan.
