Diversity among other worlds: characterization of exoplanets by direct detection
J. Schneider, A. Boccaletti, A. Aylward +34
The physical characterization of exoplanets will require to take spectra at several orbital positions. For that purpose, a direct imaging capability is necessary. Direct imaging re…
First Confirmed Detection of a Bipolar Molecular Outflow from a Young Brown Dwarf
Ngoc Phan-Bao, Basmah Riaz, Chin-Fei Lee +6
Studying the earliest stages in the birth of stars is crucial for understanding how they form. Brown dwarfs with masses between that of stars and planets are not massive enough to…
Optical variability of the ultracool dwarf TVLM 513-46546: evidence for inhomogeneous dust clouds
S. P. Littlefair, V. S. Dhillon, T. R. Marsh +3
We present multi-colour photometry of the M8.5V ultracool dwarf "pulsar" TVLM 513-46546 (hereafter TVLM 513) obtained with the triple-beam photometer ULTRACAM. Data were obtained s…
Periodic Radio and H-alpha Emission from the L Dwarf Binary 2MASSW J0746425+200032: Exploring the Magnetic Field Topology and Radius of an L Dwarf
E. Berger, R. E. Rutledge, N. Phan-Bao +6
[Abridged] We present an 8.5-hour simultaneous radio, X-ray, UV, and optical observation of the L dwarf binary 2MASSW J0746+20. We detect strong radio emission, dominated by short-…
Fifteen new T dwarfs discovered in the UKIDSS Large Area Survey
D. J. Pinfield, B. Burningham, M. Tamura +32
We present the discovery of fifteen new T2.5-T7.5 dwarfs (with estimated distances between ~24-93pc, identified in the first three main data releases of the UKIRT Infrared Deep Sky…
IPHAS discoveries of young stars towards Cyg OB2 and its southern periphery
Jorick S. Vink, Janet E. Drew, Danny Steeghs +5
We report on the discovery of over 50 strong Halpha emitting objects towards the large OB association Cyg OB2 and the HII region DR 15 on its southern periphery. This was achieved…
