JWST demonstrates exoplanet search and exozodiacal dust analysis in binary system α Cen A, indicating challenges in detection.

A candidate point source, labeled S 1, detected around α Centauri A with a signal-to-noise ratio of 4-6.
The JWST achieved unprecedented sensitivity to exozodiacal disks, with limits reaching 5-8 times that of our solar system's zodiacal cloud.
Reference star differential imaging was utilized to subtract stellar images and enhance the search for exoplanets.
The analysis emphasizes the complexities of observing dynamic binary systems and the need for further observations to confirm S 1.

Sanghi et al. (2025) studied this question.
