Protoplanetary Disk Masses in Taurus and the Orion Nebula Cluster
Presented by Nick Ballering
Steward Observatory, University of Arizona

Monday, October 1, 2018
12:00 noon in 169-336

Abstract
The masses of protoplanetary disks are a primary factor influencing the efficiency of planet formation. I will present the results of fitting radiative transfer models to the spectral energy distributions of disks in the Taurus star-forming region. Such models can provide a more accurate determination of disk masses than (sub-)mm photometry alone, while offering insight into the assumptions that are often employed when measuring disk masses. I will also highlight the results of our recent ALMA observations of disks in the Orion Nebula Cluster which reveal the effects of the cluster environment on disk properties.

About the Speaker
Nick is interested in planet formation and circumstellar disks. He earned a PhD at the University of Arizona working with George Rieke to study the structure and composition of debris disks. He is currently a postdoc at the University of Arizona working with Josh Eisner to measure the masses of protoplanetary disks in various star forming environments
