Our target object is HD15745, an F2V star with an extended scattered light disk. 27 Images were taken by the Hubble Space Telescope's (HST) Imaging Spectrograph (STIS) and its coronagraph, which helps to reveal faint structures while suppressing the star's glare. The images were captured using Angular Differential Imaging (ADI) by changing the roll angles of HST. Using Affinity Photo 2 software, the images were masked, and Python was used to perform Point Spread Function (PSF) subtraction and Principal Component (PCA) on the data. This analysis provides us with insight on the most important structures and features in the disk surrounding HD15745.
