SPHERE dynamical and spectroscopic characterization of HD142527B

R. Claudi, A. -L. Maire, D. Mesa +50

We detect the accreting low-mass companion HD142527B at a separation of 73 mas (11.4 au) from the star. No other companions with mass greater than 10 MJ are visible in the field of…

Spectral and orbital characterisation of the directly imaged giant planet HIP 65426 b

A. C. Cheetham, M. Samland, S. S. Brems +38

HIP 65426 b is a recently discovered exoplanet imaged during the course of the SPHERE-SHINE survey. Here we present new and observations of the planet from the NACO instr…

A search for accreting young companions embedded in circumstellar disks: High-contrast H imaging with VLT/SPHERE

G. Cugno, S. P. Quanz, S. Hunziker +37

Aims: We want to detect and quantify observables related to accretion processes occurring locally in circumstellar disks, which could be attributed to young forming planets. We foc…

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…

Extrasolar planets and brown dwarfs around AF-type stars. X.The SOPHIE northern sample. Combining the SOPHIE and HARPS surveys to compute the close giant planet mass-period distribution around AF-type stars

S. Borgniet, A. -M. Lagrange, N. Meunier +31

The impact of the stellar mass on the giant planet properties is still to be fully understood. Main-Sequence (MS) stars more massive than the Sun remain relatively unexplored in ra…

High-Contrast study of the candidate planets and protoplanetary disk around HD~100546

E. Sissa, R. Gratton, A. Garufi +62

The nearby Herbig Be star HD100546 is known to be a laboratory for the study of protoplanets and their relation with the circumstellar disk that is carved by at least 2 gaps. We ob…
