(Oxford University Press on behalf of the Royal Astronomical Society, 2013-07)
      We report the discovery of 76 new T dwarfs from the UKIRT Infrared Deep Sky Survey (UKIDSS) Large Area Survey (LAS). Near-infrared broad- and narrow-band photometry and spectroscopy are presented for the new objects, along ...
    • 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 ...
