Abstract Accreting protoplanets are windows into planet formation processes, and high-contrast differential imaging is an effective way to identify them. We report results from the Giant Protoplanet Survey (GAPlanetS), which collected H α imagery of 14 transitional disk host stars with Magellan Adaptive Optics System. To address twin challenges morphological complexity point-spread function instability, GAPlanetS required novel approaches for frame selection optimization Karhounen–Loéve...
Accreting protoplanets represent a window into planet formation processes. We report Hα differential imaging results from the deepest and most comprehensive accreting protoplanet survey to date, acquired with Magellan Adaptive Optics (MagAO) system's VisAO camera. The fourteen transitional disks targeted are ideal candidates for discovery due their wide, heavily depleted central cavities, wealth of non-axisymmetric circumstellar disk features evocative ongoing formation, stellar accretion....
