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…
New Planetary Systems from the Calan-Hertfordshire Extrasolar Planet Search
J. S. Jenkins, H. R. A. Jones, M. Tuomi +22
We report the discovery of eight new giant planets, and updated orbits for four known planets, orbiting dwarf and subgiant stars using the CORALIE, HARPS, and MIKE instruments as p…
A Method for Selecting M dwarfs with an Increased Likelihood of Unresolved Ultra-cool Companionship
N. J. Cook, D. J. Pinfield, F. Marocco +15
Locating ultra-cool companions to M dwarfs is important for constraining low-mass formation models, the measurement of sub-stellar dynamical masses and radii, and for testing ultra…
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…
Rapid formation of large dust grains in the luminous supernova SN 2010jl
Christa Gall, Jens Hjorth, Darach Watson +6
The origin of dust in galaxies is still a mystery. The majority of the refractory elements are produced in supernova explosions but it is unclear how and where dust grains condense…
