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…
A Search for Variability in Exoplanet Analogues and Low-Gravity Brown Dwarfs
Johanna M. Vos, Beth A. Biller, Mariangela Bonavita +18
We report the results of a -band survey for photometric variability in a sample of young, low-gravity objects using the New Technology Telescope (NTT) and the United Kingdom Inf…
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…
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-…
First scattered light detection of a nearly edge-on transition disk around the T Tauri star RY Lup
M. Langlois, A. Pohl, A. -M. Lagrange +41
Transition disks are considered sites of ongoing planet formation, and their dust and gas distributions could be signposts of embedded planets. The transition disk around the T Tau…
