dc.descriptionWe thank F. Jiménez Esteban for helpful discussion on Gaia DR2 white dwarfs. This research made use of the Sintbad database and VizieR catalogue access tool, operated at Centre de Donnees astronomiques de Strasbourg, France, the Spanish Virtual Observatory, NASA's Astrophysics Data System, and the Washington Double Star Catalog maintained at the US Naval Observatory. Financial support was provided by the Spanish MICINN under grants AYA2616-79425-C3-1/2-P, and the Conserjería de Educación, Juventud y Deporte de la Comunidad de Madrid and the Fondo Social Europeo y la Iniciativa de Empleo Juvenil (YEI) under grant PEJD-2616/TIC-2347.
dc.description.abstractThe system WDS 16329+0315 is an old, nearby, quintuple physical system in the thick Galactic disc formed by a close, but resolved, triple primary of solar metallicity, namely HD 149162, and a very wide, common-proper-motion, secondary pair, formed by the mid-M dwarf G 17-23 and the white dwarf LSPM J1633+0311S. We present an exhaustive astrometric and photometric data compilation of the system, including Gaia DR2 parallaxes and proper motions, and the first analysis of the nature of the faintest component. LSPM J1633+o311S (HD 149162 C) is a very cool white dwarf with an effective temperature of only about 5500 K, near the coolest end of the grid of theoretical models.
