The mass of Beta Pictoris c from Beta Pictoris b orbital motion

S. Lacour, J. J. Wang, L. Rodet +96

We aim to demonstrate that the presence and mass of an exoplanet can now be effectively derived from the astrometry of another exoplanet. We combined previous astrometry of Pic…

Investigating point sources in MWC 758 with SPHERE

A. Boccaletti, E. Pantin, F. Ménard +26

Context. Spiral arms in protoplanetary disks could be shown to be the manifestation of density waves launched by protoplanets and propagating in the gaseous component of the disk.…

Revealing asymmetrical dust distribution in the inner regions of HD 141569

Garima Singh, Trisha Bhowmik, Anthony Boccaletti +42

We obtained polarimetric differential imaging of a gas-rich debris disk around HD 141569A with SPHERE in the H-band to compare the scattering properties of the innermost ring at 44…

A SOPHIE RV search for giant planets around young nearby stars (YNS). A combination with the HARPS YNS survey

A. Grandjean, A. -M. Lagrange, N. Meunier +9

The search of close (a<=5 au) giant planet(GP) companions with radial velocity(RV) around young stars and the estimate of their occurrence rates is important to constrain the migra…

GRAVITY K-band spectroscopy of HD 206893 B: brown dwarf or exoplanet

J. Kammerer, S. Lacour, T. Stolker +94

We aim to reveal the nature of the reddest known substellar companion HD 206893 B by studying its near-infrared colors and spectral morphology and by investigating its orbital moti…

The SPHERE infrared survey for exoplanets (SHINE)- I Sample definition and target characterization

S. Desidera, G. Chauvin, M. Bonavita +105

Large surveys with new-generation high-contrast imaging instruments are needed to derive the frequency and properties of exoplanet populations with separations from 5 to 300…
