The building blocks of planets


Department of Physics and Astronomy

About the Project

Planets form in cold discs of dust and gas around young, newly-formed stars. Solid particles ("dust") represent only a small fraction of the disc mass, but these particles are the initial building blocks of planetesimals and planets. The trace dust component also dominates the disc opacity, so most of our observations only "see" the dust rather than the gas. In this project the student will build new computational models of dust and gas dynamics in protoplanetary discs, looking in particular at the so-called "back-reaction" of the dust on the gas.
We will use a combination of 1-D, 2-D and 3-D calculations to study disc dynamics and evolution over a wide range of time-scales. We will then use radiative transfer modelling to generate synthetic observations, in order to test our models against new data from facilities such as ALMA and the ESO VLT. The overall aim of the project is to build up a detailed understanding the key physical processes that shape the appearance and evolution of planet-forming discs.
