Investigating three Sirius-like systems with SPHERE
R. Gratton, V. D'Orazi, T. A. Pacheco +61
Sirius-like systems are wide binaries composed of a white dwarf (WD) and a companion of a spectral type earlier than M0. The WD progenitor evolves in isolation, but its wind during…
The Y dwarf population with HST: unlocking the secrets of our coolest neighbours -- I. Overview & First astrometric results
Clemence Fontanive, Luigi R. Bedin, Daniella C. Bardalez Gagliuffi
In this paper we present our project that aims at determining accurate distances and proper motions for the Y brown dwarf population using the Hubble Space Telescope. We validate t…
A wide planetary-mass companion to a young low-mass brown dwarf in Ophiuchus
Clemence Fontanive, Katelyn N. Allers, Blake Pantoja +6
We present the discovery of a planetary-mass companion to CFHTWIR-Oph 98, a low-mass brown dwarf member of the young Ophiuchus star-forming region, with a wide 200-au separation (1…
VIBES: VIsual Binary Exoplanet survey with SPHERE Upper limits on wide S-planet and S-BD frequencies, triple system discovery, and astrometric confirmation of 20 stellar binaries and three triple systems
J. Hagelberg, N. Engler, C. Fontanive +7
Recent surveys indicate that planets in binary systems are more abundant than previously thought, which is in agreement with theoretical work on disc dynamics and planet formation…
The search for disks or planetary objects around directly imaged companions: A candidate around DH Tau B
C. Lazzoni, A. Zurlo, S. Desidera +45
In recent decades, thousands of substellar companions have been discovered with both indirect and direct methods of detection. In this paper, we focus our attention on substellar c…
The SPHERE infrared survey for exoplanets (SHINE). III. The demographics of young giant exoplanets below 300 au with SPHERE
A. Vigan, C. Fontanive, M. Meyer +108
The SHINE project is a 500-star survey performed with SPHERE on the VLT for the purpose of directly detecting new substellar companions and understanding their formation and early…
