Dust traps as planetary birthsites: basics and vortex formation
James E. Owen, Juna A. Kollmeier
We present a simple model for low-mass planet formation and subsequent evolution within "transition" discs. We demonstrate quantitatively that the predicted and observed structure…
Probing X-ray photoevaporative winds through their interaction with ionising radiation in cluster environments: the case for X-ray proplyds
C. J. Clarke, James. E. Owen
We show that if young low mass stars undergo vigorous X-ray driven disc winds, these may be detected in clusters through their interaction with ionising radiation from massive star…
Astro & cosmo-chemical consequences of accretion bursts I: the D/H ratio of water
James E. Owen, Emmanuel Jacquet
The D/H ratio of water in protostellar systems is a result of both inheritance from the parent molecular cloud and isotopic exchange in the disc. A possibly widespread feature of d…
Importance of thermal diffusion in the gravo-magnetic limit cycle
James E. Owen, Philip J. Armitage
We consider the role of thermal diffusion due to turbulence and radiation on accretion bursts that occur in protoplanetary discs which contain dead zones. Using 1D viscous disc mod…
Snow-lines as probes of turbulent diffusion in protoplanetary discs
James E. Owen
Sharp chemical discontinuities can occur in protoplanetary discs, particularly at `snow-lines' where a gas-phase species freezes out to form ice grains. Such sharp discontinuities…
