The Torino Observatory Parallax Program: \n\tWhite dwarf candidates

Abstract

\n We present parallax determinations for six white dwarf\ncandidates in the Torino Observatory Parallax Program. The absolute\nparallaxes are found with precisions at the 2–3 milliarcsec level.\nFor WD 1126+185 we find a distance incompatible with being a white\ndwarf, implying an incorrect classification. For WD 2216+484 we find\nour distance is consistent with a simple DA white dwarf rather than a\ncomposite system as previously proposed in the literature. In general\nit is found that the published photometric distance is an overestimate\nof the distance found here.\n\n\n
