cds-question@unistra.frmultiple-starsradial-velocityTYC 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 (T_eff_<~6000K) primary stars. Our analysis of TYC 4110-01037-1 reveals it to be a moderately aged (<~5Gyr) solar-like star having a mass of 1.07+/-0.08M_{sun}_ and radius of 0.99+/-0.18R_{sun}_. We analyze 32 radial velocity (RV) measurements from the SDSS-III MARVELS survey as well as 6 supporting RV measurements from the SARG spectrograph on the 3.6m Telescopio Nazionale Galileo telescope obtained over a period of ~2years. The best Keplerian orbital fit parameters were found to have a period of 78.994+/-0.012days, an eccentricity of 0.1095+/-0.0023, and a semi-amplitude of 4199+/-11m/s. We determine the minimum companion mass (if sini=1) to be 97.7+/-5.8M_Jup_. The system's companion to host star mass ratio, >=0.087+/-0.003, places it at the lowest end of observed values for short period stellar companions to solar-like (T_eff_<~6000K) stars. One possible way to create such a system would be if a triple-component stellar multiple broke up into a short period, low q binary during the cluster dispersal phase of its lifetime. A candidate tertiary body has been identified in the system via single-epoch, high contrast imagery. If this object is confirmed to be comoving, we estimate it would be a dM4 star. We present these results in the context of our larger-scale effort to constrain the statistics of low-mass stellar and brown dwarf companions to FGK-type stars via the MARVELS survey.2012AJ....143..107Whttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AJ/143/107CatalogResearchIsServedByTAP VizieR generic servicerelated-toVI/135 : All-sky spectrally matched Tycho2 stars (Pickles+, 2010)V/136 : Teff and metallicities for Tycho-2 stars (Ammons+, 2006)I/259 : The Tycho-2 Catalogue (Hog+ 2000)J/A+A/552/A78 : Solar like stars radial velocities (Zechmeister+, 2013)J/A+A/525/A95 : Search for brown-dwarf companions of stars (Sahlmann+, 2011)J/ApJ/736/19 : Kepler planetary candidates.
