Spectroscopic signatures of youth in low-mass kinematic candidates of young moving groups
M. C. Gálvez-Ortiz, M. Kuznetsov, J. R. A. Clarke +12
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 gr…
Spectroscopy and kinematics of low-mass members of young moving groups
M. C. Galvez-Ortiz, J. R. A. Clarke, D. J. Pinfield +8
We study a target sample of 68 low-mass objects (with spectral types in the range M4.5-L1) previously selected via photometric and astrometric criteria, as possible members of five…
Discovery of the first wide L dwarf + giant binary system and eight other ultra-cool dwarfs in wide binaries
Z. H. Zhang, D. J. Pinfield, A. C. Day-Jones +11
We identify 806 ultra-cool dwarfs from their SDSS riz photometry (of which 34 are newly discovered L dwarfs) and obtain proper motions through cross matching with UKIDSS and 2MASS.…
Ultra-cool dwarfs: new discoveries, proper motions, and improved spectral typing from SDSS and 2MASS photometric colors
Z. H. Zhang, R. S. Pokorny, H. R. A. Jones +6
Aims. We try to identify ultra-cool dwarfs from the seventh Data Release of the Sloan Digital Sky Survey (SDSS DR7) with SDSS i-z and r-z colors. We also obtain proper motion data…
Ultra-cool Dwarfs from Large Area Surveys
Z. H. Zhang, H. R. A. Jones, D. J. Pinfield +2
We selected brown dwarf candidates from the seventh Data Release of the Sloan Digital Sky Survey (SDSS DR7) with new photometric selectioncriteria based on a parameteriaztion of we…
A search for southern ultracool dwarfs in young moving groups
J. R. A. Clarke, D. J. Pinfield, M. C. Galvez-Ortiz +7
We associate 132 low-mass ultracool dwarfs in the southern hemisphere as candidate members of five moving groups using photometric and astrometric selection techniques. Of these ob…
New, nearby bright southern ultracool dwarfs
T. R. Kendall, H. R. A. Jones, D. J. Pinfield +5
We report the discovery of twenty-one hitherto unknown bright southern ultracool dwarfs with spectral types in the range M7 to L5.5, together with new observations of a further thr…
The Liverpool-Edinburgh High Proper Motion Survey
Richard S. Pokorny, Hugh R. A. Jones, Nigel C. Hambly
We present a catalogue of 6206 stars which have proper motions exceeding 0.18 arcsec/yr with an R-band faint magnitude limit of 19.5 mag. This catalogue has been produced using Sup…
