The SPHERE infrared survey for exoplanets (SHINE): II. Observations, data reduction and analysis, detection performances, and initial results
(2021)Astronomy & AstrophysicsContext. In recent decades, direct imaging has confirmed the existence of substellar companions (exoplanets or brown dwarfs) on wide orbits (>10 au) around their host stars. In striving to understand their formation and evolution mechanisms, in 2015 we initiated the SPHERE infrared survey for exoplanets (SHINE), a systematic direct imaging survey of young, nearby stars that is targeted at exploring their demographics. Aims. We aim to ...Journal Article -

Post conjunction detection of β Pictoris b with VLT/SPHERE
(2019)Astronomy & AstrophysicsContext. With an orbital distance comparable to that of Saturn in the solar system, β Pictoris b is the closest (semi-major axis ≃9 au) exoplanet that has been imaged to orbit a star. Thus it offers unique opportunities for detailed studies of its orbital, physical, and atmospheric properties, and of disk-planet interactions. With the exception of the discovery observations in 2003 with NaCo at the Very Large Telescope (VLT), all following ...Journal Article -
Observations of fast-moving features in the debris disk of AU Mic on a three-year timescale: Confirmation and new discoveries
(2018)Astronomy & AstrophysicsContext. The nearby and young M star AU Mic is surrounded by a debris disk in which we previously identified a series of large-scale arch-like structures that have never been seen before in any other debris disk and that move outward at high velocities. Aims. We initiated a monitoring program with the following objectives: (1) track the location of the structures and better constrain their projected speeds, (2) search for new features ...Journal Article
