The JWST Early Release Science Program for Direct Observations of Exoplanetary Systems VIII: patchy forsterite and enstatite clouds in the atmosphere of VHS 1256 b, retrieval lessons learned and outlook to the future
Niall Whiteford, Jacqueline K. Faherty, Ben Burningham +123
JWST defines a new era for the data-driven approach of retrieval modelling, which has become a cornerstone tool for the statistical inference of exoplanetary and brown dwarf proper…
Resolving core-envelope degeneracies in giant planets and sub-Neptunes: constraining the equivalence in the presence of dilute gradients
Christian Wilkinson, Benjamin Charnay, Stéphane Mazevet +4
The widespread recognition of dilute, "fuzzy" cores in giant planets and massive volatile mantles in sub-Neptunes has made interior modelling a highly degenerate, multi-dimensional…
Destructuring the disk of AB Aurigae: Dynamics and accretion
Anthony Boccaletti, Emmanuel Di Folco, Anne Dutrey +23
In this paper, we present near-IR polarized images of the AB Aur disk at three epochs spanning 3.85 years with SPHERE/IRDIS, as well as Halpha images obtained with SPHERE/ZIMPOL at…
Scheduling Ground-Based Telescope Observations with Uncertain Nights
Thomas Rahab Lacroix, Pierre Lemaire, Anne-Marie Lagrange +2
The observation of celestial objects is a fundamental activity in astronomy. Ground-based and space telescopes are used to gather electromagnetic radiation from space, allowing ast…
Characterization of debris disks observed with SPHERE
N. Engler, J. Milli, N. Pawellek +33
This study aims to characterize debris disks observed with SPHERE across multiple programs, with the goal of identifying systematic trends in disk morphology, dust mass, and grain…
Direct imaging discovery of a young giant planet orbiting on Solar System scales
T. Stolker, M. Samland, L. B. F. M. Waters +102
HD 135344 AB is a young visual binary system that is best known for the protoplanetary disk around the secondary star. The circumstellar environment of the A0-type primary star, on…
