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 ...
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 ...
