A library of near-infrared integral field spectra of young M-L dwarfs
M. Bonnefoy, G. Chauvin, A. -M. Lagrange +5
We present a library of near-infrared (1.1-2.45 microns) medium-resolution (R~1500-2000) integral field spectra of 15 young M6-L0 dwarfs, composed of companions with known ages and…
Deep search for companions to probable young brown dwarfs
G. Chauvin, J. Faherty, A. Boccaletti +10
We have obtained high contrast images of four nearby, faint, and very low mass objects 2MASSJ04351455-1414468, SDSSJ044337.61+000205.1, 2MASSJ06085283-2753583 and 2MASSJ06524851-57…
Near-infrared integral-field spectra of the planet/brown dwarf companion AB Pic b
M. Bonnefoy, G. Chauvin, P. Rojo +5
Chauvin et al. 2005 imaged a co-moving companion at ~260 AU from the young star AB Pic A. Evolutionary models predictions based on J H K photometry of AB Pic b suggested a mass of…
VLT/NACO Deep imaging survey of young, nearby austral stars
G. Chauvin, A. -M. Lagrange, M. Bonavita +10
Since November 2002, we have conducted the largest deep imaging survey of the young, nearby associations of the southern hemisphere. Our goal is detection and characterization of s…
The young, tight and low mass binary TWA22AB: a new calibrator for evolutionary models ? Orbit, spectral types and temperatures determination
M. Bonnefoy, G. Chauvin, C. Dumas +7
Tight binaries discovered in young, nearby associations, with known distances, are ideal targets to provide dynamical mass measurements to test the physics of evolutionary models a…
Astrometric and Spectroscopic Confirmation of a Brown Dwarf Companion to GSC 08047-00232
G. Chauvin, A. -M. Lagrange, F. Lacombe +8
We report VLT/NACO imaging observations of the stars GSC 08047-00232 and HIP 6856, probable members of the large Tucana-Horologium association. During our previous ADONIS/SHARPII d…
