Primeval very low-mass stars and brown dwarfs. I. Six new L subdwarfs, classification and atmospheric properties
Z. H. Zhang, D. J. Pinfield, M. C. Galvez-Ortiz +10
We have conducted a search for L subdwarf candidates within the photometric catalogues of the UKIRT Infrared Deep Sky Survey and Sloan Digital Sky Survey. Six of our candidates are…
A large spectroscopic sample of L and T dwarfs from UKIDSS LAS: peculiar objects, binaries, and space density
F. Marocco, H. R. A. Jones, A. C. Day-Jones +7
We present the spectroscopic analysis of a large sample of late-M, L, and T dwarfs from UKIDSS. Using the YJHK photometry from ULAS and the red-optical photometry from SDSS we sele…
Discovery of a new Y dwarf: WISE J030449.03-270508.3
D. J. Pinfield, M. Gromadzki, S. K. Leggett +21
We present a new Y dwarf, WISE J030449.03-270508.3, confirmed from a candidate sample designed to pick out low temperature objects from the WISE database. The new object is typed Y…
The extremely red L dwarf ULAS J222711004547 - dominated by dust
F. Marocco, A. C. Day-Jones, P. W. Lucas +8
We report the discovery of a peculiar L dwarf from the UKIDSS LAS, ULAS J222711-004547. The very red infrared photometry (MKO J-K = 2.790.06, WISE W1-W2 = 0.650.05) of UL…
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…
