The polar orbit of the warm Neptune GJ436b seen with VLT/ESPRESSO

V. Bourrier, M. R. Zapatero Osorio, R. Allart +24

GJ436b might be the prototype of warm Neptunes that have undergone late migration induced by an outer companion. Precise determination of the orbital architecture of such systems i…

Lessons learned from SPHERE for the astrometric strategy of the next generation of exoplanet imaging instruments

A. -L. Maire, M. Langlois, P. Delorme +14

Measuring the orbits of directly-imaged exoplanets requires precise astrometry at the milliarcsec level over long periods of time due to their wide separation to the stars ($\gtrsi…

Disk Evolution Study Through Imaging of Nearby Young Stars (DESTINYS): A close low mass companion to ET Cha

C. Ginski, F. Ménard, Ch. Rab +25

To understand the formation of planetary systems, one needs to understand the initial conditions of planet formation, i.e. the young gas-rich planet forming disks. Spatially resolv…

X-ray emission in the enigmatic CVSO 30 system

S. Czesla, P. C. Schneider, M. Salz +3

CVSO 30 is a young, active, weak-line T Tauri star; it possibly hosts the only known planetary system with both a transiting hot-Jupiter and a cold-Jupiter candidate (CVSO 30 b and…

Mapping of shadows cast on a protoplanetary disk by a close binary system

V. D'Orazi, R. Gratton, S. Desidera +47

For a comprehensive understanding of planetary formation and evolution, we need to investigate the environment in which planets form: circumstellar disks. Here we present high-cont…

In-depth study of moderately young but extremely red, very dusty substellar companion HD206893B

P. Delorme, T. Schmidt, M. Bonnefoy +47

The substellar companion HD206893b has recently been discovered by direct imaging of its disc-bearing host star with the SPHERE instrument. We investigate the atypical properties o…
