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 ...
Fragmentation favoured in discs around higher mass stars
(Oxford University Press, 2020-03)
We investigate how a protoplanetary disc’s susceptibility to gravitational instabilities and fragmentation depends on the mass of its host star. We use 1D disc models in conjunction with 3D smoothed particle hydrodynamics ...
