Worlds Next Door. IV. Mapping the Late Stages of Giant Planet Evolution with a Precise Dynamical Mass and Luminosity for Ind Ab

Aniket Sanghi, William Thompson, James Mang +21

We present new JWST/NIRCam 4-5 m (F410M, F430M) and JWST/MIRI 18-25 m (F1800W, F2100W, F2550W) imaging detections of the nearby (3.6 pc) cold (275 K) gas giant exoplanet $Î…

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

Aniket Sanghi, Charles Beichman, Dimitri Mawet +14

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 w…

Integrated photonic-based coronagraphic systems for future space telescopes

Niyati Desai, Lorenzo König, Emiel Por +38

The detection and characterization of Earth-like exoplanets around Sun-like stars is a primary science motivation for the Habitable Worlds Observatory. However, the current best te…
