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…
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.…
