    • 3D kinematics of white dwarfs from the SPY project. II. 
      Pauli, E.-M.; Napiwotzki, R.; Heber, U.; Altmann, Martin; Odenkirchen, M. (EDP SCIENCES S A, 2006-02)
      We present the kinematics of a sample of 398 DA white dwarfs from the SPY project (ESO SN Ia Progenitor surveY) and discuss kinematic criteria for distinguishing of thin-disk, thick-disk, and halo populations. This is the ...
    • Discovery of a T dwarf plus white dwarf binary system 
      Day-Jones, A. C.; Pinfield, D. J.; Ruiz González, María Teresa; Beaumont, H.; Burningham, B.; Gallardo, J.; Gianninas, A.; Bergeron, P.; Napiwotzki, R.; Jenkins, James Stewart; Zhang, Z. H.; Murray, D. N.; Catalán, S.; Gomes, J. (WILEY-BLACKWELL, 2011-01)
      We present the discovery of the first T dwarf + white dwarf binary system LSPM 1459+0857 AB, confirmed through common proper motion and spectroscopy. The white dwarf is a high proper motion object from the LSPM catalogue ...
