A brown dwarf companion to the intermediate-mass star HR6037
N. Huelamo, D. E. A. Nuernberger, V. D. Ivanov +8
In the course of an imaging survey we have detected a visual companion to the intermediate-mass star HR 6037. In this letter, we present two epoch observations of the binary with N…
First Results From VLT NACO Apodizing Phase Plate: 4-micron Images of the Exoplanet beta Pictoris b
Sascha P. Quanz, Michael R. Meyer, Matthew Kenworthy +9
Direct imaging of exoplanets requires both high contrast and high spatial resolution. Here, we present the first scientific results obtained with the newly commissioned Apodizing P…
The 2008 Outburst in the Young Stellar System Z CMa: The First Detection of Twin Jets
Emma Whelan, Catherine Dougados, Marshall Perrin +11
The Z CMa binary is understood to undergo both FU Orionis (FUOR) and EX Orionis (EXOR) type outbursts. While the SE component has been spectro- scopically identified as an FUOR, th…
The 2008-2009 outburst of the young binary system Z CMa unraveled by interferometry with high spectral resolution
Fabien Malbet, Myriam Benisty, Catherine Dougados +7
Z CMa is a young binary system consisting of an Herbig primary and a FU Ori companion. Both components seem to be surrounded by active accretion disks and a jet was associated to t…
The 2008 outburst in the young stellar system ZCMa: I. Evidence of an enhanced bipolar wind on the AU-scale
M. Benisty, F. Malbet, C. Dougados +15
Accretion is a fundamental process in star formation. Although the time evolution of accretion remains a matter of debate, observations and modelling studies suggest that episodic…
A giant planet imaged in the disk of the young star Beta Pictoris
A. -M. Lagrange, M. Bonnefoy, G. Chauvin +8
Here we show that the ~10 Myr Beta Pictoris system hosts a massive giant planet, Beta Pictoris b, located 8 to 15 AU from the star. This result confirms that gas giant planets form…
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…
