Multi-Conjugate Adaptive Optics images of the Trapezium Cluster
H. Bouy, J. Kolb, E. Marchetti +3
Multi-Conjugate Adaptive Optics (MCAO) combines the advantages of standard adaptive optics, which provides high contrast and high spatial resolution, and of wide field ~1' imaging.…
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…
The lower mass function of the young open cluster Blanco 1: from 30 Mjup to 3 Mo
Estelle Moraux, Jerome Bouvier, John Stauffer +2
We performed a deep wide field optical survey of the young (~100-150 Myr) open cluster Blanco1 to study its low mass population well down into the brown dwarf regime and estimate i…
Cool objects: From SED fitting to age estimation
A. Bayo, D. Barrado y Navascues, M. Morales-Calderon +4
The physical properties of almost any kind of astronomical object can be derived by fitting synthetic spectra or photometry extracted from theoretical models to observational data.…
SPITZER: Accretion in Low Mass Stars and Brown Dwarfs in the Lambda Orionis Cluster
D. Barrado y Navascues, J. R. Stauffer, M. Morales-Calderon +6
We present multi-wavelength optical and infrared photometry of 170 previously known low mass stars and brown dwarfs of the 5 Myr Collinder 69 cluster (Lambda Orionis). The new phot…
A Splinter Session on the Thorny Problem of Stellar Ages
Eric E. Mamajek, David Barrado y Navascues, Sofia Randich +4
Accurate stellar ages remain one of the most poorly constrained, but most desired, astronomical quantities. Here we briefly summarize some recent efforts to improve the stellar age…
