The impact of mergers in the mass distribution of white dwarfs
J. Isern, S. Catalan, E. Garcia-Berro +1
Recent surveys have allowed to derive the white dwarf mass distribution with reasonable accuracy. This distribution shows a noticeable degree of structure that it is often attribut…
The brightest pure-H ultracool white dwarf
S. Catalan, P. -E. Tremblay, D. J. Pinfield +9
We report the identification of LSR J0745+2627 in the United Kingdom InfraRed Telescope Infrared Deep Sky Survey (UKIDSS) Large Area Survey (LAS) as a cool white dwarf with kinemat…
White dwarfs as physics laboratories: the case of axions
J. Isern, L. Althaus, S. Catalan +4
White dwarfs are almost completely degenerate objects that cannot obtain energy from thermonuclear sources, so their evolution is just a gravothermal cooling process. Recent improv…
Discovery of the benchmark metal poor T8 dwarf BD+01 2920B
D. J. Pinfield, B. Burningham, N. Lodieu +20
We have searched the WISE first data release for widely separated (<10,000AU) late T dwarf companions to Hipparcos and Gliese stars. We have discovered a new binary system containi…
