" The ALMA revolution: gas and dust in planet-forming disks "

Nienke van der Marel

(IfA Manoa)

The study of protoplanetary disks was for a long time based on indirect measurements of gas and dust, limiting our understanding of planet formation. The arrival of ALMA has revolutionized our view of the structure of these disks. The Early Science ALMA observations in the last few years have revealed rings, asymmetries, dust/gas segregation, gas dynamics, evidence for dust trapping and vortices, and many more exciting phenomena that have been predicted for decades in physical models of disks. The structures provide evidence for the presence of embedded planets, which can be confirmed by direct imaging such as done with Subaru. In this talk I will discuss the findings of ALMA observations and their implications for finding the embedded planets.

Seminars are also held at JAC, CFHT, and IfA.
