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…
Disappearance of the extended main sequence turn-off in intermediate age clusters as a consequence of magnetic braking
C. Georgy, C. Charbonnel, L. Amard +8
Extended MS turn-offs are features commonly found in the colour-magnitude diagrams of young and intermediate age (less than about 2 Gyr) massive star clusters, where the MS turn-of…
ALMA polarimetric studies of rotating jet/disk systems
F. Bacciotti, J. M. Girart, M. Padovani +9

HIP 65426 b is a recently discovered exoplanet imaged during the course of the SPHERE-SHINE survey. Here we present new and observations of the planet from the NACO instr…
Overview of the European Extremely Large Telescope and its instrument suite
B. Neichel, D. Mouillet, E. Gendron +3

Why Chromatic Imaging Matters
Joel Sanchez-Bermudez, Florentin Millour, Fabien Baron +15
During the last two decades, the first generation of beam combiners at the Very Large Telescope Interferometer has proved the importance of optical interferometry for high-angular…
Kinetic modeling of the electromagnetic precursor from an axisymmetric binary pulsar coalescence
Benjamin Crinquand, Benoît Cerutti, Guillaume Dubus
The recent detection of gravitational waves associated with a binary neutron star merger revives interest in interacting pulsar magnetospheres. Current models predict that a signif…
The Disk Substructures at High Angular Resolution Project (DSHARP): IV. Characterizing substructures and interactions in disks around multiple star systems
Nicolás Kurtovic, Laura Pérez, Myriam Benisty +11
To characterize the substructures induced in protoplanetary disks by the interaction between stars in multiple systems, we study the mm continuum and the CO…
Status of the MEDUSAE post-processing method to detect circumstellar objects in high-contrast multispectral images
Faustine Cantalloube, Marie Ygouf, Laurent Mugnier +3
The MEDUSAE method (Multispectral Exoplanet Detection Using Simultaneous Aberration Estimation) is dedicated to the detection of exoplanets and disks features in multispectral high…
The Disk Substructures at High Angular Resolution Project (DSHARP): X. Multiple rings, a misaligned inner disk, and a bright arc in the disk around the T Tauri star HD 143006
Laura M. Pérez, Myriam Benisty, Sean M. Andrews +14
We present a detailed analysis of new ALMA observations of the disk around the T-Tauri star HD 143006, which at 46 mas (7.6 au) resolution reveal new substructures in the 1.25 mm c…
