    • 76 T dwarfs from the UKIDSS LAS: benchmarks, kinematics and an updated space density 
      Burningham, Ben; Cardoso, C. V.; Smith, L.; Leggett, S. K.; Smart, R. L.; Mann, A. W.; Dhital, S.; Lucas, P. W.; Tinney, C. G.; Pinfield, D. J.; Zhang, Z.; Morley, C.; Saumon, D.; Aller, K.; Littlefair, S. P.; Homeier, D.; Lodieu, N.; Deacon, N.; Marley, M. S.; Spaandonk, L. van; Baker, D.; Allard, F.; Andrei, A. H.; Canty, J.; Clarke, J.; Day-Jones, A. C.; Dupuy, T.; Fortney, J. J.; Gomes, J.; Ishii, M.; Jones, H. R. A.; Liu, M.; Magazzú, A.; Marocco, F.; Murray, D. N.; Rojas-Ayala, B.; Tamura, M. (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 ...
    • A deep WISE search for very late type objects and the discovery of two halo/thick-disc T dwarfs: WISE ... 
      Pinfield, D. J.; Gomes, J.; Day Jones, A. C.; Leggett, S. K.; Gromadzki, M.; Burningham, B.; Ruiz González, María Teresa; Kurtev, R.; Cattermole, T.; Cardoso, C.; Lodieu, N.; Faherty, J.; Littlefair, S.; Smart, R.; Irwin, M.; Clarke, J. R. A.; Smith, L.; Lucas, P. W.; Gálvez Ortiz, M. C.; Jenkins, James Stewart; Jones, H. R. A.; Rebolo, L.; Béjar, V. J. S.; Gauza, B. (Oxford University Press, 2014)
      A method is defined for identifying late-T and Y dwarfs in WISE down to low values of signalto- noise. This requires a WISE detection only in theW2-band and uses the statistical properties of the WISE multiframe measurements ...
    • New constraints on the formation and settling of dust in the atmospheres of young M and L dwarfs 
      Manjacavas, E.; Bonnefoy, M.; Schlieder, J. E.; Allard, F.; Rojo Rubke, Patricio; Goldman, B.; Chauvin, G.; Homeier, D.; Lodieu, N.; Henning, Thomas (2014-04)
      Context. Gravity modifies the spectral features of young brown dwarfs (BDs). A proper characterization of these objects is crucial for the identification of the least massive and latest-type objects in star-forming regions, ...
