White dwarfs within 13 pc: insights from ultraviolet spectroscopy

Mairi W. O'Brien, Pier-Emmanuel Tremblay, Boris T. Gänsicke +10

We present a comprehensive multi-wavelength spectroscopic and photometric analysis of the 44 confirmed white dwarfs within 13 pc of the Sun. Combining flux-calibrated ultraviolet s…
