Tuesday 30 May 2017The ins and outs of circumstellar disks

Claire Davies - University of Exeter

Protoplanetary disks have been found to be ubiquitous across all masses of star formation - forming as a result of angular momentum conservation during the gravitational collapse of a rotating cloud core. In addition, disks of proto-planetary debris have also been found around older pre-main-sequence and main sequence stars. In this talk, I will discuss recently submitted results of the SONS JCMT Legacy Survey of debris disks, focussing in particular on radius estimations for the spatially extended subsample. I will also present the results of ongoing analysis of interferometric data obtained with CHARA and the VLTI for the innermost regions of the circumstellar disk of RY Tau and the circum-primary and circum-secondary disks of the CO Ori binary system.
