Reset option doesn't work. Probing the young circumplanetary environment of a directly-imaged exoplanet through a rare transit event Among the thousands of known exoplanets, Beta Pic b is the only directly imaged exoplanet with a nearly edge-on orbit that may transit its host star. We show that the latest astrometric measurements rule out a transit by the planet at >10-sigma significance, but we are certain that the Hill sphere of the planet will transit. Unfortunately, Beta Pic will not be visible from the ground during the entire ingress of its Hill sphere. With a period of ~20 years and no other system like it, this Hill sphere transit provides a rare opportunity to study the evolving circumplanetary environment of a young and well-characterized exoplanet. Thus we propose a modest HST campaign to photometrically search for signatures of the planet's large scale circumplanetary material. The existence of such material is plausible given that Beta Pic's young age is similar to that of the ring-bearing J1407b system. Using the exquisite photometric precision offered by WFC3 in spatial scanning mode, the data may detect gaps in a circumplanetary disk, indicative of rings carved out by newly-formed satellites. Given the sparse observational data for circumplanetary environments, non-detections will also be valuable for constraining the timescales relevant to circumplanetary material and moon formation. If photometric variations are detected with HST, these results would have enormous significance to the community since ground-based facilities could subsequently be used to monitor egress at higher cadence. A search for signatures of Beta Pic b's large scale circumplanetary material.
