Abstract |
The β Pictoris b Hill Sphere transit occurred between early-2017 and early-2018. During this event, high precision, high cadence photometry of β Pictoris was obtained by the bRing (β Pictoris b Ring) and ASTEP (Antarctic Search for Transiting ExoPlanets) ground-based observatories, the BRITE (Bright Target Explorer) satellite, and the HST (Hubble Space Telescope). The data from each source were combined and analyzed to search for evidence of occultation of the star by circumplanetary matter. While the star's pulsations were detected, none of the surveys detected any unexplained fluctuations, which might have been due to circumplanetary matter. This poster presents the overall light curve of β Pictoris during the Hill sphere transit and presents preliminary estimates of upper limits on the amount of circumplanetary dust at a wide range of orbital radii around the exoplanet β Pictoris b. |
