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…
Discovery of a Debris Disk Around TWA 20
Skyler Palatnick, Maxwell A. Millar-Blanchaer, Jingwen Zhang +20
We report the discovery of a debris disk surrounding the M3 star, TWA 20, revealed by JWST coronagraphic observations using the Near-infrared Camera (NIRCam). With reference-star d…
Habitable World Discovery and Characterization: Coronagraph Concept of Operations and Data Post-Processing
Michael W. McElwain, Dimitri Mawet, Jean-Baptiste Ruffio +11
The discovery and characterization of habitable worlds was the top scientific recommendation of the Astro2020 decadal survey and is a key objective of the Habitable Worlds Observat…
A Striking First Impression: CGI Commissioning Observations of the AB Aurigae Protoplanetary System
Thayne Currie, Kellen Lawson, Erica Dykes +1
For one of the first set of Roman Coronagraph project images, we propose to target AB Aurigae. AB Aurigae is a complex and visually stunning system, surrounded by a gas rich protop…
Follow-Up Exploration of the TWA 7 Planet-Disk System with JWST NIRCam
Katie A. Crotts, Aarynn L. Carter, Kellen Lawson +39
The young M-star TWA 7 hosts a bright and near face-on debris disk, which has been imaged from the optical to the submillimeter. The disk displays multiple complex substructures su…
Probing the Outskirts of M Dwarf Planetary Systems with a Cycle 1 JWST NIRCam Coronagraphy Survey
Ellis Bogat, Joshua E. Schlieder, Kellen D. Lawson +18
The population of giant planets on wide orbits around low-mass M dwarf stars is poorly understood, but the unprecedented sensitivity of JWST NIRCam coronagraphic imaging now provid…
JWST-TST High Contrast: Living on the Wedge, or, NIRCam Bar Coronagraphy Reveals CO in the HR 8799 and 51 Eri Exoplanets' Atmospheres
William O. Balmer, Jens Kammerer, Laurent Pueyo +19
High-contrast observations with JWST can reveal key composition and vertical mixing dependent absorption features in the spectra of directly imaged planets across the 3-5 m wave…
