Tracing water vapor and ice during dust growth
Sebastiaan Krijt, Fred J. Ciesla, Edwin A. Bergin
The processes that govern the evolution of dust and water (in the form of vapor or ice) in protoplanetary disks are intimately connected. We have developed a model that simulates d…
Hydrocarbon emission rings in protoplanetary disks induced by dust evolution
Edwin A. Bergin, Fujun Du, L. Ilsedore Cleeves +4
We report observations of resolved C2H emission rings within the gas-rich protoplanetary disks of TW Hya and DM Tau using the Atacama Large Millimeter Array (ALMA). In each case th…
On the Commonality of 10-30AU Sized Axisymmetric Dust Structures in Protoplanetary Disks
Ke Zhang, Edwin A. Bergin, Geoffrey A. Blake +4
An unsolved problem in step-wise core-accretion planet formation is that rapid radial drift in gas-rich protoplanetary disks should drive mm-/meter-sized particles inward to the ce…
