    • 47 new T dwarfs from the UKIDDS large area survey 

      Burningham, B.; Pinfield, D.J.; Lucas, P.W.; Leggett, S.K.; Deacon, Niall; Tamura, M.; Tinney, C.G.; Lodieu, N.; Zhang, Z.; Huelamo, N.; Jones, H.R.A.; Murray, D.N.; Mortlock, D.J.; Patel, M.; Barrado y Navascues, D.; Zapatero Osorio, M.R.; Ishii, M.; Kuzuhara, M.; Smart, R.L. (2010)
      We report the discovery of 47 new T dwarfs in the Fourth Data Release (DR4) from the Large Area Survey (LAS) of the United Kingdom Infrared Telescope (UKIRT) Infrared Deep Sky Survey with spectral types ranging from T0 to ...

    • Discovery of a T dwarf + white dwarf binary system 

      Day-Jones, Avril; Pinfield, D.J.; Ruiz, M.; Beaumont, H.; Burningham, B.; Gallardo, J.; Gianninas, A.; Bergeron, P.; Napiwotzki, Ralf; Jenkins, J.S.; Zhang, Z.H.; Murray, D.N.; Catalan, Silvia; Ines Gomes, Joana (2011)
      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 ...

    • The discovery of a very cool binary system 

      Burningham, B.; Leggett, S.K.; Lucas, P.W.; Pinfield, D.J.; Smart, R.L.; Day-Jones, A.C.; Jones, H.R.A.; Murray, D.N.; Nickson, E.; Tamura, M.; Zhang, Z.; Lodieu, N.; Tinney, C.G.; Zapatero Osorio, M.R. (2010)
      We report the discovery of a very cool d/sdL7+T7.5p common proper motion binary system, SDSS J1416+13AB, found by cross-matching the United Kingdom Infrared Telescope (UKIRT) Infrared Deep Sky Survey (UKIDSS) Large Area ...

    • The discovery of an M4+T8.5 binary system 

      Burningham, B.; Pinfield, D.J.; Leggett, S.K.; Tinney, C.G.; Liu, M.C.; Homeier, D.; West, A.A.; Day-Jones, A.C.; Huelamo, N.; Dupuy, T.J.; Zhang, Z.; Murray, D.N.; Lodieu, N.; Navascues, D.B.Y.; Folkes, S.; Galvez-Ortiz, M.C.; Jones, H.R.A.; Lucas, P.W.; Calderon, M.M.; Tamura, M. (2009)
      We report the discovery of a T8.5 dwarf, which is a companion to the M4 dwarf Wolf 940. [Please see original online abstract for complete version with correct notation]

    • Parallaxes and physical properties of 11 mid-to-late T dwarfs 

      Marocco, F.; Smart, R.L.; Jones, H.R.A.; Burningham, B.; Lattanzi, M.G.; Leggett, S.K.; Lucas, P.W.; Tinney, C.G.; Adamson, A.; Evans, D. W.; Lodieu, N.; Murray, D.N.; Pinfield, D.J.; Tamura, M. (2010)
      Aims. We present parallaxes of 11 mid-to-late T dwarfs observed in the UKIRT Infrared Deep Sky Survey. We use these results to test the reliability of model predictions in magnitude–color space, determine a magnitude-spectral ...
