Unexpected debris disks

JWST's unprecedented sensitivity in the infrared has enabled for the first time direct imaging search and characterisation of sub-Jupiter exoplanets. With this goal, the survey program 6005 was executed in Cycle 3, complementing GO programs 4050 and 5835, and providing a set of uniform observations of over 150 young stars.Besides exoplanet investigation, another science return of these programs was the serendipitous detection of several debris disks associated to target stars.In this poster I include the current reduction and analysis of the F200W and F444W observations of the debris disk surrounding the G-type star HD202917. These observations reveal the morphology and dust distribution of the material hinted in previous photometric mid-IR observations. Thanks to the sensitivity of the data, we will be able to identify and investigate any point sources detected, and to obtain deep contrast curves that establish accurate mass limits for possible substellar companions. Additionally, by combining these new observations with archival data, we will be able to provide the first characterisation of the dust morphology and composition, and lay the base for future studies.
