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…
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.…
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…
NAHUAL: A cool spectrograph for planets of ultra-cool objects
E. W. Guenther, E. L. Martin, D. Barrado y Navascues +1
We present the status of an ongoing study to built a a high resolution near infrared Echelle spectrograph (NAHUAL) for the 10.4-m-Gran Telescopio Canarias (GTC) which will be espec…
The Collinder 69 cluster in the context of the Lambda Orionis SFR
David Barrado y Navascues, J. R. Stauffer, J. Bouvier +1
The Lambda Orionis Star Forming Region is a complex structure which includes the Col 69 (Lambda Orionis) cluster and the B30 & B35 dark clouds. We have collected deep optical photo…
Lambda Orionis: A 0.02-50 Msun Initial Mass Function
David Barrado y Navascues, J. R. Stauffer, J. Bouvier
The Lambda Orionis Star Forming Region is dominated by the O8 III star lambda^1 Ori. Among other structures, it includes a CO and a dust ring whose diameter is about nine deg, the…
