Worlds Next Door. III. Indirect Evidence for Enhanced Atmospheric Metallicity and/or the Presence of Water Clouds in the Nearest Jupiter-analog ϵ Eri b

We present the most sensitive direct imaging search for the nearest ( d = 3.2 pc) Jupiter-analog exoplanet, ϵ  Eri b, with JWST/NIRCam coronagraphy between 4 and 5  μ m (F444W). We achieve a 5 σ contrast sensitivity ≈3.0 × 10 ^−7 (Δ ≈ 16.3 mag) in the F444W filter at the expected planet separation o...
