    • Cool dwarfs stars from the Torino Observatory Parallax Program 

      Smart, R.L.; Ioannidis, G.; Jones, H.R.A.; Bucciarelli, B.; Lattanzi, M.G. (2010)
      Aims. We investigate and parameterize high proper motion red stars in the Torino Observatory Parallax Program. Methods. Observations of 27 objects were made over the period 1994–2001 on the 1.05 m Torino telescope. The ...

    • Discovery of a peculiar DQ white dwarf 

      Carollo, D.; Hodgkin, S.T.; Spagna, A.; Smart, R.L.; Lattanzi, M.G.; McLean, B.J.; Pinfield, D.J. (2002)

    • The distance to the cool T9 brown dwarf ULAS J003402.77-005206.7 

      Smart, R.L.; Jones, H.R.A.; Lattanzi, M.G.; Leggett, S.K.; Warren, S.J.; Adamson, A.J.; Burningham, B.; Casali, M.; Evans, D.W.; Irwin, M.J.; Pinfield, D.J. (2010)
      Aims. We demonstrate the feasibility of determining parallaxes for nearby objects with the Wide Field Camera on the United Kingdom Infrared Telescope (UKIRT) using the UKIRT Infrared Deep Sky Survey as a first epoch. We ...

    • NPARSEC : NTT Parallaxes of Southern Extremely Cool objects. Goals, targets, procedures and first results 

      Smart, R.L.; Tinney, C.G.; Bucciarelli, B.; Marocco, F.; Abbas, U.; Andrei, A.; Bernardi, G.; Burningham, B.; Cardoso, C.; Costa, E.; Crosta, M.T.; Dapra, M.; Day-Jones, A.; Goldman, B.; Jones, H.R.A.; Lattanzi, M.G.; Leggett, S.K.; Lucas, P.W.; Mendez, R.; Penna, J.L.; Pinfield, D.J.; Smith, Leigh; Sozzetti, A.; Vecchiato, A. (2013-08)
      The discovery and subsequent detailed study of T dwarfs have provided many surprises and pushed the physics and modelling of cool atmospheres in unpredicted directions. Distance is a critical parameter for studies of these ...

    • 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 ...

    • Parallaxes of southern extremely cool objects. I. : Targets, proper motions, and first results 

      Andrei, A.H.; Smart, R.L.; Penna, J.L.; d'Avila, V.A.; Bucciarelli, B.; Camargo, J.I.B.; Crosta, M.T.; Dapra, M.; Goldman, B.; Jones, H.R.A.; Lattanzi, M.G.; Nicastro, L.; Pinfield, D.J.; da Silva Neto, D. N.; Teixeira, R. (2011)
      We present results from the PARallaxes of Southern Extremely Cool objects ( PARSEC) program, an observational program begun in 2007 April to determine parallaxes for 122 L and 28 T southern hemisphere dwarfs using the Wide ...
