Debris disks

Mark Wyatt’s group at the IoA focusses on debris disks. These are the disks of asteroid, comets, dust and gas found around nearby main sequence stars. As a component of the planetary system, moreover one which is often readily detectable, studying their structure provides valuable information on the architecture and formation history of the planetary system. The group uses a combination of observations (e.g., Herschel, ALMA, LBTI, VLTI) to detect and characterise the disks, as well as analytical and numerical techniques to study dynamical interactions between planets and disk material, and the physical processes that lead to the creation of dust and gas in the systems. Among other related topics, the group also studies protoplanetary disks, accretion onto white dwarfs, the Solar System, and more general planetary system dynamics problems.
