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…
The GJ 504 system revisited. Combining interferometric, radial velocity, and high contrast imaging data
M. Bonnefoy, K. Perraut, A. -M. Lagrange +79
The G-type star GJ504A is known to host a 3 to 35 MJup companion whose temperature, mass, and projected separation all contribute to make it a test case for the planet formation th…
Imaging radial velocity planets with SPHERE
A. Zurlo, D. Mesa, S. Desidera +37
We present observations with the planet finder SPHERE of a selected sample of the most promising radial velocity (RV) companions for high-contrast imaging. Using a Monte Carlo simu…
Dynamical masses of M-dwarf binaries in young moving groups: I - The case of TWA 22 and GJ 2060
L. Rodet, M. Bonnefoy, S. Durkan +48
Evolutionary models are widely used to infer the mass of stars, brown dwarfs, and giant planets. Their predictions are thought to be less reliable at young ages ( 200 Myr) and i…
VLT/SPHERE astrometric confirmation and orbital analysis of the brown dwarf companion HR 2562 B
A. -L. Maire, L. Rodet, C. Lazzoni +46
Context. A low-mass brown dwarf has been recently imaged around HR 2562 (HD 50571), a star hosting a debris disk resolved in the far infrared. Interestingly, the companion location…
Discovery of a brown dwarf companion to the star HIP 64892
A. Cheetham, M. Bonnefoy, S. Desidera +89
We report the discovery of a bright, brown dwarf companion to the star HIP 64892, imaged with VLT/SPHERE during the SHINE exoplanet survey. The host is a B9.5V member of the Lower-…
