JWST observed our closest solar twin, Cen A, with the MIRI coronagraph in F1550C (15.5 m) at three distinct epochs between August 2024 and April 2025. For the first time wit…
NIRCam yells at cloud: JWST MIRI imaging can directly detect exoplanets of the same temperature, mass, age, and orbital separation as Saturn and Jupiter
Rachel Bowens-Rubin, James Mang, Mary Anne Limbach +9
NIRCam and MIRI coronagraphy have successfully demonstrated the ability to directly image young sub-Jupiter mass and mature gas-giant exoplanets. However, these modes struggle to r…
Evidence for Variable Accretion onto PDS 70 c and Implications for Protoplanet Detections
