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…
Blue not brown: UKIDSS T dwarfs with suppressed K-band flux
D. N. Murray, B. Burningham, H. R. A Jones +13
We have used blue near-infrared colours to select a group of 12 spectroscopically-confirmed UKIDSS T dwarfs later than T4. From amongst these we identify the first two kinematic ha…
GRB 090902B: afterglow observations and implications
S. B. Pandey, C. A. Swenson, D. A. Perley +30
The optical-infrared afterglow of the LAT-detected long duration burst, GRB 090902B, has been observed by several instruments. The earliest detection by ROTSE-IIIa occurred 80 minu…
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.…
Infrared Spectroscopy and Analysis of Brown Dwarf and Planetary Mass Objects in the Orion Nebula Cluster
D. J. Weights, P. W. Lucas, P. F. Roche +2
We present near-infrared long slit and multi-slit spectra of low mass brown dwarf candidates in the Orion Nebula Cluster. The long slit data were observed in the H- & K-bands using…
Discovery of a widely separated UCD-WD binary
A. C. Day-Jones, D. J. Pinfield, R. Napiwotzki +6
We present the discovery of the widest known ultracool dwarf - white dwarf binary. This binary is the first spectroscopically confirmed widely separated system from our target samp…
