We report the discovery of a candidate brown dwarf (BD) or a very low mass stellar companion (MARVELS-5b) to the star HIP 67526 from the Multi-object Apache point observatory Radial Velocity Exoplanet Large-area Survey (MARVELS). The radial velocity

We present an eccentric, short-period brown dwarf candidate orbiting the active, slightly evolved subgiant star TYC 2087-00255-1, which has effective temperature Teff = 5903±42 K, surface gravity log(g) = 4.07±0.16 (cgs), and metallicity [Fe/H] =

TYC 4110-01037-1 has a low-mass stellar companion, whose small mass ratio and short orbital period are atypical among binary systems with solar-like (Teff 6000 K) primary stars. Our analysis of TYC 4110-01037-1 reveals it to be a moderately aged ( 5

Context. We have obtained BVRI photometry for 21 stellar fields located in directions towards the central 3.5° of the Galaxy. Each field is 10 × 10 arcmin in size, and a total of ∼2 × 105 stars were measured. Aims. Previous analyses based on 2 M

This study proposes an observing program focused on the investigation of the stellar magnetism and dynamo evolution in cool active solar-like stars. More mainly in the solar analogs and twins. Observations of stars of our base were carried out with t
