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 deep WISE search for very late type objects and the discovery of two halo/thick-disk T dwarfs: WISE 0013+0634 and WISE 0833+0052
D. J. Pinfield, J. Gomes, A. C. Day-Jones +21
A method is defined for identifying late T and Y dwarfs in WISE down to low values of signal-to-noise. This requires a WISE detection only in the W2-band and uses the statistical p…
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…
Two new ultra-cool benchmark systems from WISE+2MASS
J. I. Gomes, D. J. Pinfield, F. Marocco +6
We have used the 2MASS all-sky survey and the WISE to look for ultracool dwarfs that are part of multiple systems containing main sequence stars. We cross-matched L dwarf candidate…
