ACCRETION OUTBURSTS IN SELF-GRAVITATING PROTOPLANETARY DISKS

Constraining the masses of planets in protoplanetary discs from the presence or absence of vortices - comparison with ALMA observations
(Published by Oxford University Press on behalf of the Royal Astronomical Society, 2020-02)A massive planet in a protoplanetary disc will open a gap in the disc material. A steep gap edge can be hydrodynamically unstable, which results in the formation of vortices that can act as tracers for the presence of ... -
Dynamics of dusty vortices - I. Extensions and limitations of the terminal velocity approximation
(Published by Oxford University Press on behalf of the Royal Astronomical Society, 2019-10)Motivated by the stability of dust laden vortices, in this paper we study the terminal velocity approximation equations for a gas coupled to a pressureless dust fluid and present a numerical solver for the equations embedded ... -

The observational anatomy of externally photoevaporating planet-forming discs - I. Atomic carbon
(Oxford University Press, 2020-03)We demonstrate the utility of C I as a tracer of photoevaporative winds that are being driven from discs by their ambient UV environment. Commonly observed CO lines only trace these winds in relatively weak UV environments ...
