Worlds Next Door: A Candidate Giant Planet Imaged in the Habitable Zone of α Centauri A. II. Binary Star Modeling, Planet and Exozodi Search, and Sensitivity Analysis

The James Webb Space Telescope (JWST) observed our closest solar twin, α Centauri A ( α Cen A), with the Mid-Infrared Instrument in the F1550C (15.5 μ m) coronagraphic imaging mode at three distinct epochs between 2024 August and 2025 April.
