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…
Calibration of an Analog-to-Digital Conversion Nonlinearity in JWST/NIRISS
Shashank Dholakia, Shishir Dholakia, Benjamin J. S. Pope +4
We quantify an unusual flux-dependent systematic which is periodic in raw counts in flight data from the James Webb Space Telescope's Near Infrared Imager and Slitless Spectrograph…
AMIGO: a Data-Driven Calibration of the JWST Interferometer
Louis Desdoigts, Benjamin Pope, Max Charles +8
The James Webb Space Telescope (JWST) hosts a non-redundant Aperture Masking Interferometer (AMI) in its Near Infrared Imager and Slitless Spectrograph (NIRISS) instrument, providi…
Image reconstruction with the JWST Interferometer
Max Charles, Louis Desdoigts, Benjamin Pope +7
Flying on board the James Webb Space Telescope (JWST) above Earth's turbulent atmosphere, the Aperture Masking Interferometer (AMI) on the NIRISS instrument is the highest-resoluti…
JWST/MIRI coronagraphic search for planets in systems with gapped exoKuiper belts and proper motion anomalies
R. Bendahan-West, S. Marino, A. L. Carter +17
Over the past decade, ALMA has uncovered a range of substructures within exoKuiper belts, pointing to a population of undetected planets. With JWST's sensitivity, we now have the o…
JWST/NIRCam observations of HD~92945 debris disk: An asymmetric disk with a gap
C. Lazzoni, R. Bendahan-West, S. Marino +9
We present the first observations of the HD92945 debris disk obtained with JWST, targeting this nearby K0V star located at 21.54 pc from the Sun. High-contrast coronagraphic imagin…
