Testing the fragmentation limit in the Upper Sco association
N. Lodieu, N. C. Hambly, P. D. Dobbie +4
We present the results of a deep (J ~ 21 mag at 5 sigma) infrared photometric survey of a 0.95 square degree area in the central region of the Upper Sco association. The photometri…
Adaptive optics observations of the T10 ultracool dwarf UGPSJ072227.51-054031.2
H. Bouy, J. Girard, E. L. Martin +2
With a spectral type of T10, UGPS J072227.51-054031.2 is one of the coolest objects known to date in the solar neighborhood. Multiple systems are relatively common among early and…
Short-term spectroscopic monitoring of two cool dwarfs with strong magnetic fields
E. W. Guenther, M. R. Zapatero Osorio, A. Mehner +1
Context: There is now growing evidence that some brown dwarfs (BDs) have very strong magnetic fields, and yet their surface temperatures are so low that the coupling is expected to…
A very cool brown dwarf in UKIDSS DR1
S. J. Warren, D. J. Mortlock, S. K. Leggett +21
(abridged) We report the discovery of a very cool brown dwarf, ULAS J003402.77-005206.7 (ULAS J0034-00), identified in UKIDSS DR1. We provide optical, near-infrared, and mid-infrar…
