Exploring the Evolution of Circumstellar Disks with ALMA

John Carpenter , Joint ALMA Observatory
ALMA is providing new opportunities to explore the evolution of circumstellar disks. From snapshot surveys of protoplanetary disks in nearby star forming regions, to sensitive high-resolution images of young disks, and to surveys of old debris disks, ALMA is tracing the structure and properties of disks at all evolutionary stages. This talk will present recent ALMA observations that are contributing to our understanding of the properties of protoplanetary and debris disks. I will first summarize the results from recent ALMA surveys that are establishing the demographics of protoplanetary disks between ages of 1 and 10 Myr. I will also present new high-resolution images of 20 protoplanetary disks from an ALMA Large Program that is designed to determine the prevalence of substructure (e.g., rings, spirals, and gaps) in young protoplanetary disks. Finally, I will present new ALMA data for a debris disk around a ~ 100 Myr old solar analog and discuss the implications for planet formation in this system.
