Protoplanetary Disks



Protoplanetary disks are circumstellar disks of dust and gas around young (Myr-old) stars. They provide the raw material to build up planets hence their evolution and dispersal is critical to understand when and what type of planets can form.



Ongoing projects:

The Evolution of Disk Winds – new NSF funded project

Earths in Other Solar Systems (EOS) – NASA funded astrobiology research program, see the EOS website for Objectives, Team, and major results

SLICK – Scaling Laws in Circumstellar disKs – NSF funded, based on an approved ALMA Cycle 2 proposal to measure the disk masses of all protoplanetary disks in the Chamaeleon I star-forming region [2013.1.00437.S, I. Pascucci PI]. Results published in: Pascucci et al. 2016, Hendler et al. 2017, Long et al. 2017, Manara et al. 2017, Mulders et al. 2017
