VERY-LOW-MASS STELLAR AND SUBSTELLAR COMPANIONS TO SOLAR-LIKE STARS FROM MARVELS. III. A SHORT-PERIOD BROWN DWARF CANDIDATE AROUND AN ACTIVE G0IV SUBGIANT

We present an eccentric, short-period brown dwarf candidate orbiting the active, slightly evolved subgiant star TYC 2087-00255-1, which has effective temperature T sub(eff) = 5903 + or - 42 K, surface gravity log(g) = 4.07 + or - 0.16 (cgs), and metallicity [Fe/H] = -0.23 + or - 0.07. From our 38 ra...
