Discovery of Seven Companions to Intermediate-mass Stars with Extreme Mass Ratios in the Scorpius–Centaurus Association
We report the detection of seven low-mass companions to intermediate-mass stars (SpT B/A/F; ~ 1.5–4.5 M_⊙) in the Scorpius–Centaurus (Sco–Cen) Association using nonredundant aperture maskingExpand

An M-dwarf star in the transition disk of Herbig HD 142527: physical parameters and orbital elements.
S.L. acknowledges fruitful discussions with S. Casassus about the existence of HD 142527B and the inner disk of HD 142527A. This research made use of Astropy, a community-developed core PythonExpand

Discovery of a planetary-mass companion within the gap of the transition disk around PDS 70
Context. Young circumstellar disks are the birthplaces of planets. Their study is of prime interest to understand the physical and chemical conditions under which planet formation takes place. OnlyExpand

Discovery of a warm, dusty giant planet around HIP 65426
Aims. The SHINE program is a high-contrast near-infrared survey of 600 young, nearby stars aimed at searching for and characterizing new planetary systems using VLT/SPHERE’s unprecedentedExpand

Hint of curvature in the orbital motion of the exoplanet 51 Eridani b using 3 years of VLT/SPHERE monitoring
Context. The 51 Eridani system harbors a complex architecture with its primary star forming a hierarchical system with the binary GJ 3305AB at a projected separation of 2000 au, a giant planetExpand

Non-redundant Aperture Masking Interferometry (AMI) and segment phasing with JWST-NIRISS
The Aperture Masked Interferometry (AMI) mode on JWST-NIRISS is implemented as a 7-hole, 15% throughput, non-redundant mask (NRM) that operates with 5-8% bandwidth filters at 3.8, 4.3, and 4.8Expand

Long baseline observations of HD100546 with ALMA: a possible circumplanetary disk detected in dust continuum and gas kinematics
Giant planets growing in a circumstellar disk interact dynamically with the whole disk, and planetary growth is thought to be regulated by the circumplanetary disk (CPD) and its immediateExpand

Post-conjunction detection of β Pictoris b with VLT/SPHERE
Context. 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 offersExpand

ISPY -- NaCo Imaging Survey for Planets around Young stars. Discovery of an M dwarf in the gap between HD 193571 and its debris ring
Context. The interaction between low-mass companions and the debris discs they reside in is still not fully understood. A debris disc can evolve due to self-stirring, a process in which planetesimalsExpand

Observations of fast-moving features in the debris disk of AU Mic on a three-year timescale : Confirmation and new discoveries
Context. 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 otherExpand
