Journal ArticleDOI
A giant planet candidate near a young brown dwarf - Direct VLT/NACO observations using IR wavefront sensing
Gael Chauvin,Anne-Marie Lagrange,Christophe Dumas,Barry Zuckerman,David Mouillet,Inseok Song,J. L. Beuzit,Patrick Lowrance +7 more
TL;DR: In this article, the authors presented deep VLT/NACO infrared imaging and spectroscopic observations of the brown dwarf 2MASSWJ 1207334−393254, obtained during the on-going adaptive optics survey of southern young, nearby associations.

TL;DR: The data, combined with radio and X-ray observations, suggest that XRF 060218 is an intrinsically weak and soft event, rather than a classical GRB observed off-axis, which extends the GRB–supernova connection to X-rays flashes and fainter supernovae, implying a common origin.
Journal ArticleDOI
Discovery of a Probable 4-5 Jupiter-mass Exoplanet to HD 95086 by Direct Imaging
J. Rameau,Gael Chauvin,A-M. Lagrange,Anthony Boccaletti,Sascha P. Quanz,Mickael Bonnefoy,Julien Girard,P. Delorme,Silvano Desidera,Hubert Klahr,Christoph Mordasini,Christophe Dumas,Mariangela Bonavita +12 more
TL;DR: In this article, the authors reported the discovery of a probable companion orbiting the young (10-17 Myr), dusty, early-type (A8) star HD 95086 at 56 AU in L' (3.8 {mu}m) images.
