AGE-PRO

The ALMA Survey of Gas Evolution in PROtoplanetary Disks

AGE-PRO is the first ALMA Large Program specifically designed to systematically trace the evolution of gas in protoplanetary disks. Through deep molecular line observations of 30 disks spanning the typical gas disk lifetime, AGE-PRO provides an unprecedented view into how the gas content in disks evolves over time.

By combining these observations with advanced thermo-chemical modeling, we deliver robust measurements of disk gas mass and size for our 30-disk sample. These findings are compared against key theoretical frameworks of disk evolution, including turbulent viscosity and magneto-hydrodynamical disk winds.

AGE-PRO is a collaboration of more than 20 astronomers across multiple institutions (meet the team here!). Our results have been published in a coordinated set of scientific publications (AGE-PRO I through XII), and all associated datasets are now publicly available through our dedicated AGE-PRO Data page. Additional publications and data releases will be announced on this site.
