"The Dynamics of Planet Formation"

Abstract:

Over the past decade, observations of protoplanetary disks have revealed numerous substructures in their dust distributions at both (sub)millimeter and near-infrared (NIR) wavelengths. These features provide a blueprint for the wide range of physical properties and orbital architectures observed in exoplanetary systems. Although the origins of these disk substructures remain uncertain, their multiplicity reflects the underlying gas dynamics, as dust grains are coupled to gas motion. By examining the motion of gas within these disks, we can investigate the physical processes that govern disk evolution and planet formation. In this talk, I will present an overview of recent and upcoming science results from the exoALMA Large Program, a sub-millimeter planet-hunting campaign that employs molecular line observations to uncover the complex gas kinematics of protoplanetary disks.
