In this work we identify 775 WD+AFGK candidates from TGAS (The Tycho-Gaia Astrometric Solution) and Gaia Data Release 2 (DR2), a well-defined sample of stars with available parallaxes, and we measure radial velocities (RVs) for 275 of them with the aim of identifying close binaries. The RVs have been measured from high-resolution spectra obtained at the Xinglong 2.16m Telescope and the San Pedro Martir 2.12m Telescope and/or from available LAMOST DR6 (low-resolution) and RAVE DR5 (medium-resolution) spectra. We identify 23 WD+AFGK systems displaying more than 3{sigma} RV variation among 151 systems for which the measured values are obtained from different nights. Our WD+AFGK binary sample contains both AFGK dwarfs and giants, with a giant fraction ~43%. The close binary fractions we determine for the WD+AFGK dwarf and giant samples are ~24% and ~15%, respectively. We also determine the stellar parameters (i.e., effective temperature, surface gravity, metallicity, mass, and radius) of the AFGK companions with available high-resolution spectra. The stellar parameter distributions of the AFGK companions that are members of close and wide binary candidates do not show statistically significant differences.2020ApJ...905...38Rhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/905/38CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toI/259 : The Tycho-2 Catalogue (Hog+ 2000)III/218 : ELODIE archive (Prugniel+, 2001)I/337 : Gaia DR1 (Gaia Collaboration, 2016)II/335 : Revised cat. of GALEX UV sources (GUVcat_AIS GR6+7) (Bianchi+ 2017)III/279 : RAVE 5th data release (Kunder+, 2017)I/347 : Distances to 1.33 billion stars in Gaia DR2 (Bailer-Jones+, 2018)I/345 : Gaia DR2 (Gaia Collaboration, 2018)V/164 : LAMOST DR5 catalogs (Luo+, 2019)V/156 : LAMOST DR7 catalogs (Luo+, 2019)J/AJ/131/1184 : A recalibration of opt. photometry (Maiz-Apellaniz+, 2006)J/MNRAS/382/1377 : SDSS WD main-sequence binaries (Rebassa-Mansergas+, 2007)J/MNRAS/399/2063 : LMC red giants in D sequence (Nicholls+, 2009)J/AJ/148/81 : APASS BVgri phot. of RAVE stars.
