Abstract
We discuss the Gaia Data Release 1 (September 2016) and preliminary work
on maximising the benefit for cool white dwarf (WD) science in advance
of the full parallax catalogue which will appear around one year later
in DR2. The Tycho catalogue is used in conjunction with the
all-sky ground based astrometric/ photometric SuperCOSMOS Sky
Survey in order to identify candidate faint common proper motion objects
to the Tycho stars. Gaia DR1 is supplemented by the Tycho-Gaia
Astrometric Solution catalogue containing some 2 million parallaxes with
Hipparcos-like precision for Tycho stars. While hotter, brighter
WDs are present in Tycho, cooler examples are much rarer (if present at
all) and CPM offers one method to infer precision distances for a
statistically useful sample of these very faint WDs.
