Albus 1: a very bright white dwarf candidate.


Abstract (from CDS):

We have serendipitously discovered a previously unknown, bright source (BT=11.75±0.07 mag) with a very blue VT-Kscolor, which we have named Albus 1. A photometric and astrometric study using Virtual Observatory tools has shown that it possesses an appreciable proper motion and magnitudes and colors very similar to those of the well-known white dwarf G191-B2B. We consider Albus 1 as a DA-type white dwarf located at about 40 pc. If its nature is confirmed, Albus 1 would be the sixth brightest isolated white dwarf in the sky, which would make it an excellent spectrophotometric standard.
