| Abstract: |
Our spectroscopic survey has confirmed 195 newly identified white dwarfs, 106 of which are within 40 pc of the Sun. These stars were observed during 8 observation campaigns from 2009 May to 2010 October, as part of an ongoing spectroscopic census aimed at obtaining a complete sample of white dwarfs within 40 pc of the Sun. White dwarf candidates are identified from the Northern part of the SUPERBLINK proper motion database, allowing us to investigate stars down to a proper motion limit as low as 40 mas yr-1. This sample minimizes the kinematic bias and has the potential to provide a statistically complete census of white dwarfs to a significantly larger distance. We believe that our catalog of white dwarfs within 40 parsecs of the Sun will significantly increase the completeness of the current census. |
