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 ...

Clarke, J. R. A.; Pinfield, D. J.; Gálvez Ortiz, M. C.; Jenkins, James Stewart; Burningham, B.; Deacon, N. R.; Jones, Hugh; Pokorny, R. S.; Barnes, J. R.; Day-Jones, A. C. (2010)We associate 132 low-mass ultracool dwarfs in the southern hemisphere as candidate members of five moving groups (MGs) using photometric and astrometric selection techniques. Of these objects, we present high-resolution ...

Gálvez Ortiz, M. C.; Kuznetsov, M.; Clarke, J. R. A.; Pavlenko, Ya. V.; Folkes, S. L.; Pinfield, D. J.; Jones, H. R. A.; Jenkins, James Stewart; Barnes, J. R.; Burningham, B.; Day Jones, A. C.; Martín, E. L.; García Pérez, A. E.; Burgo, C. del; Pokorny, R. S. (Oxford University Press, 2014)We present a study of age-related spectral signatures observed in 25 young low-mass objects that we have previously determined as possible kinematic members of five young moving groups: the Local Association (Pleiades ...

Day Jones, A. C.; Marocco, F.; Pinfield, D. J.; Zhang, Z. H.; Burningham, B.; Deacon, N.; Ruiz González, María Teresa; Gallardo, J.; Jones, H. R. A.; Lucas, P. W.; Jenkins, James Stewart; Gomes, J.; Folkes, S. L.; Clarke, J. R. A. (Oxford University Press on behalf of the Royal Astronomical Society, 2013)We present a new sample of mid-L to mid-T dwarfs with effective temperatures of 1100– 1700 K selected from the UKIDSS Large Area Survey (LAS) and confirmed with infrared spectra from X-shooter/Very Large Telescope .
