The census of the Solar neighbourhood is still incomplete, as demonstrated byrecent discoveries of many objects within 5-10 pc from the Sun. The area aroundthe mid-plane and bulge of the Milky Way presents the most difficulties insearches for such nearby objects, and is therefore deficient in the knownpopulation. This is largely due to high stellar densities encountered.Spectroscopic, photometric and kinematic characterization of these objectsallows better understand the local mass function, the binary fraction, andprovides new interesting targets for more detailed studies. We report thespectroscopic follow-up and characterisation of 12 bright high PM objects,identified from the VISTA Variables in Via Lactea survey (VVV). We used the1.9-m telescope of the South African Astronomical Observatory (SAAO) forlow-resolution optical spectroscopy and spectral classification, and theMPG/ESP 2.2m telescope Fiber-fed Extended Range Optical Spectrograph (FEROS)high-resolution optical spectroscopy to obtain the radial and space velocitiesfor three of them. Six of our objects have co-moving companions. We derivedoptical spectral types and photometric distances, and classified all of them asK and M dwarfs within 27-264 pc of the Sun. Finally, we found that one of thesources, VVV J141421.23-602326.1 (a co-moving companion of VVVJ141420.55-602337.1), appears to be a rare massive white dwarf that maybe closeto the ZZ Ceti instability strip. Many of the objects in our list areinteresting targets for exoplanet searches.
