First light of the VLT planet finder SPHERE. I. Detection and characterization of the sub-stellar companion GJ 758 B
A. Vigan, M. Bonnefoy, C. Ginski +72
GJ758 B is a brown dwarf companion to a nearby (15.76 pc) solar-type, metal-rich (M/H = +0.2 dex) main-sequence star (G9V) that was discovered with Subaru/HiCIAO in 2009. From prev…
News from the CFHT/ESPaDOnS spectropolarimeter
C. Moutou, L. Malo, N. Manset +2
The ESPaDOnS spectropolarimeter has been in use on the Canada-France-Hawaii Telescope (CFHT) since 2004, for studying stars, galactic objects and planets. ESPaDOnS is used in queue…
Magnetic activity and hot Jupiters of young Suns: the weak-line T Tauri stars V819 Tau and V830 Tau
JF Donati, E Hébrard, G Hussain +19
We report results of a spectropolarimetric and photometric monitoring of the weak-line T Tauri stars (wTTSs) V819 Tau and V830 Tau within the MaTYSSE programme, involving the ESPaD…

We describe in this work the BASS survey for brown dwarfs in young moving groups of the solar neighborhood, and summarize the results that it generated. These include the discovery…
BANYAN. VI. Discovery of a companion at the brown dwarf/planet-mass limit to a Tucana-Horologium M dwarf
Étienne Artigau, Jonathan Gagné, Jacqueline Faherty +5
We report the discovery of a substellar companion to 2MASS J02192210-3925225, a young M6 candidate member of the Tucana-Horologium association (30 - 40 Myr). This L4 compan…
