Searching For Planets in Protoplanetary Disks
Herbig Ae/Be (HAeBe) stars are classified as 2-10 solar mass pre-main sequence stars with circumstellar disks. As a result, they are excellent candidates for observing exoplanets in the formative stages of their evolution. By constructing and then subtracting a model PSF from object frames, we are able to obtain an image of the circumstellar disk and any planets that are located within it. Using this technique, we are searching through the archival HST images of object HD100546, which is known to host at least one planet that has been detected at near-infrared wavelengths by other telescopes. Using a few different processing algorithms we are looking to see if this planet is detectable in HST images taken more than ten years ago.
