Kepler's short-period exoplanet population has revealed evolutionary featuressuch as the Radius Valley and the Hot Neptune desert that are likely sculptedby atmospheric loss over time. These findings suggest that the primordialplanet population is different from the Gyr-old Kepler population, andmotivates exoplanet searches around young stars. Here, we present pterodactyls, a data reduction pipeline specifically built to address the challenges indiscovering exoplanets around young stars and to work with TESS Primary Mission30-min cadence photometry, since most young stars were not pre-selected TESS2-min cadence targets. pterodactyls builds on publicly available and testedtools in order to extract, detrend, search, and vet transiting young planetcandidates. We search five clusters with known transiting planets:Tucana-Horologium Association, IC 2602, Upper Centaurus Lupus, Ursa Major andPisces Eridani. We show that pterodactyls recovers seven out of the eightconfirmed planets and one out of the two planet candidates, most of which wereinitially detected in 2-min cadence data. For these clusters, we conductinjection-recovery tests to characterize our detection efficiency, and computean intrinsic planet occurrence rate of 49+-20% for sub-Neptunes and Neptunes(1.8-6 Re) within 12.5 days, which is higher than Kepler's Gyr-old occurrencerates of 6.8+-0.3%. This potentially implies that these planets have shrunkwith time due to atmospheric mass loss. However, a proper assessment of theoccurrence of transiting young planets will require a larger sample unbiased toplanets already detected. As such, pterodactyls will be used in future work tosearch and vet for planet candidates in nearby clusters and moving groups.
