Parallaxes of five L Dwarfs with a Robotic Telescope
Y. Wang, H. R. A. Jones, R. L. Smart +14
We report the parallax and proper motion of five L dwarfs obtained with observations from the robotic Liverpool Telescope. Our derived proper motions are consistent with published…
Parallaxes of Southern Extremely Cool objects (PARSEC) II: Spectroscopic Follow-up and Parallaxes of 52 Targets
F. Marocco, A. H. Andrei, R. L. Smart +8
We present near-infrared spectroscopy for 52 ultracool dwarfs, including two newly discovered late-M dwarfs, one new late-M subdwarf candidate, three new L and four new T dwarfs. W…
A catalogue of bright (K < 9) M dwarfs
J. Frith, D. J. Pinfield, H. R. A. Jones +8
Using the Position and Proper Motion Extended-L (PPMXL) catalogue, we have used optical and near-infrared colour cuts together with a reduced proper motion cut to find bright M dwa…
A spectroscopic and proper motion search of Sloan digital Sky Survey: red subdwarfs in binary systems
Z. H. Zhang, D. J. Pinfield, B. Burningham +13
Red subdwarfs in binary systems are crucial for both model calibration and spectral classification. We search for red subdwarfs in binary systems from a sample of high proper motio…
NPARSEC: NTT Parallaxes of Southern Extremely Cool objects. Goals, targets, procedures and first results
R. L. Smart, C. G. Tinney, B. Bucciarelli +21
The discovery and subsequent detailed study of T dwarfs has provided many surprises and pushed the physics and modeling of cool atmospheres in unpredicted directions. Distance is a…
Seventy six T dwarfs from the UKIDSS LAS: benchmarks, kinematics and an updated space density
Ben Burningham, C. V. Cardoso, L. Smith +34
We report the discovery of 76 new T dwarfs from the UKIDSS Large Area Survey (LAS). Near-infrared broad and narrow-band photometry and spectroscopy are presented for the new object…
