A Misaligned Debris Disk relative to the Host Star CPD-72 2713 from JWST/NIRCam Imaging

Jingwen Zhang, Maxwell A. Millar-Blanchaer, Kellen Lawson +17

Observations of debris disks provide a valuable window to investigate the formation and evolution of planetary systems. We present high-contrast JWST/NIRCam observations of CPD-72…

Worlds Next Door: A Candidate Giant Planet Imaged in the Habitable Zone of Cen A. I. Observations, Orbital and Physical Properties, and Exozodi Upper Limits

Charles Beichman, Aniket Sanghi, Dimitri Mawet +27

We report on coronagraphic observations of the nearest solar-type star, Cen A, using the MIRI instrument on the James Webb Space Telescope. With three epochs of observation (Au…

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 wit…

ESCAPE project: testing active observing strategies for high-contrast imaging in space on the HiCAT testbed

Alexis Lau, Élodie Choquet, Lisa Altinier +6

The Roman Space Telescope will be a critical mission to demonstrate high-contrast imaging technologies allowing for the characterisation of exoplanets in reflected light. It will d…

ESCAPE project. CAPyBARA: a Roman Coronagraph simulator for post-processing methods development

Lisa Altinier, Élodie Choquet, Arthur Vigan +2

The Roman Coronagraph Instrument will be the first space facility equipped with deformable mirrors (DMs). These will lead to reach a contrast of or better in a dark hole…

A new atmospheric characterization of the sub-stellar companion HR\,2562\,B with JWST/MIRI observations

Nicolás Godoy, Elodie Choquet, Eugene Serabyn +8

Context: HR2562B is a planetary-mass companion located 0.56arcsec (19au) from its host star. It is one of a few L/T transitional objects orbiting a young star. This companion provi…

ESCAPE project: fundamental detection limits of JWST/NIRCam coronographic observations

N. Godoy, E. Choquet, L. Altinier +4

In this study, we explored the fundamental contrast limit of NIRCam coronagraphy observations, representing the achievable performance with post-processing techniques. This limit i…

ESCAPE project: investigating active observing strategies and post-processing methods for exoplanet high-contrast imaging with future space missions

Elodie Choquet, Lisa Altinier, Nicolás Godoy +3

The search for biosignatures in potentially habitable exoplanets is one of the major astrophysics' drivers for the coming decades, and the prime science goal of the HWO NASA missio…
