LPL Colloquium: Dr. Feng Long

Observing Planet Formation with ALMA

Planets are assembled within disks that orbit around young stars. How these disks evolve from primordial gas and dust into the diverse planetary architecture is not well understood. With the powerful Atacama Large Millimeter/submillimeter Array (ALMA), we are now able to study these planet-forming disks in great detail, which have soon transformed our understanding of the planet formation process. In this talk, I will present recent results from ALMA disk surveys, emphasizing new insights on planet formation revealed from the dust grain distributions in disks. In particular, I will discuss the emergence and cause of disk substructures (e.g., concentric gaps and rings, spiral arms), the implications of these features on disk evolution, and how to utilize them to search for young planets.
