The puzzle of the formation of T8 dwarf Ross 458c
Josefine Gaarn, Ben Burningham, Jacqueline K. Faherty +7
At the lowest masses, the distinction between brown dwarfs and giant exoplanets is often blurred and literature classifications rarely reflect the deuterium burning boundary. Atmos…
Low-resolution near-infrared spectroscopic signatures of unresolved ultracool companions to M dwarfs
N. J. Cook, D. J. Pinfield, F. Marocco +14
We develop a method to identify the spectroscopic signature of unresolved L-dwarf ultracool companions, which compares the spectra of candidates and their associated control stars…
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 LOFAR mini-survey for low-frequency radio emission from the nearest brown dwarfs
Ben Burningham, M. Hardcastle, J. D. Nichols +9
We have conducted a mini-survey for low-frequency radio emission from some of the closest brown dwarfs to the Sun with rapid rotation rates: SIMP J013656.5+093347, WISEPC J150649.9…
Identifying the ejected population from disintegrating multiple systems
A. K. P. Yip, D. J. Pinfield, R. Kurtev +2
Kinematic studies of the Hipparcos catalogue have revealed associations that are best explained as disintegrating multiple systems, presumably resulting from a dynamical encounter…
The substellar companion in the eclipsing white dwarf binary SDSS J141126.20+200911.1
S. P. Littlefair, S. L. Casewell, S. G. Parsons +14
We present high time resolution SDSS- and SDSS- light curves of the primary eclipse in SDSS J141126.20+200911.1, together with time-resolved X-Shooter spectroscopy and near…
