![HCI directly images exoplanetary systems. (a) Preprocessed exposure, where star light dominates the entire field of view. (b) Originally buried in (a), four exoplanets exist around star HR 8799 in total intensity after postprocessing (e.g., [66]). (c) Spirals around star MWC 758 in polarized light. Note: The units are detector count s−1 pixel−1 , and central regions with 8 pixel radii (1 pixel = 12.25 mas; [34]) are blocked by coronagraph and thus inaccessible. (d) Preprocessed 1024 × 1024 pixel reference image without target disk. (e) Cropped to central 256 × 256 pixel area. (f) Preprocessed reference data mapped to linear space. -- astro-ph.EP](https://i0.wp.com/astrobiology.com/wp-content/uploads/2025/06/POLARIS-A-High-contrast.png?resize=1200%2C717&ssl=1)
With over 1,000,000 images from more than 10,000 exposures using state-of-the-art high-contrast imagers (e.g., Gemini Planet Imager, VLT/SPHERE) in the search for exoplanets, can artificial intelligence (AI) serve as a […]

Polarimetry Of Exoplanet-Exomoon Systems
We investigated the potential of polarimetric observations in the optical wavelength range for the detection of exomoons and the characterization of exoplanet-exomoon systems.

Feasibility Study on Retrieving Exoplanetary Cloud Cover Distributions Using Polarimetry
Context. As a new growing field, exocartography aims to map the surface features of exoplanets that are beyond the resolution of traditional observing techniques. While photometric approaches have been discussed […]
