CO snow lines are stabilised by the vertical transport of volatiles
Alfie Robinson, James E. Owen, Richard A. Booth
Volatile evolution in protoplanetary discs determines the compositional evolution of forming planets. Below their sublimation temperatures, volatiles freeze out from the vapour pha…
Characterizing the bolometric-photoevaporative transition in young sub-Neptunes with radiation-hydrodynamic simulations
William Misener, Matthäus Schulik, Matthäus Schulik +2
Hydrodynamic atmospheric escape plays a central role in shaping the demographics of small, close-in exoplanets. Two mechanisms have been proposed to drive mass loss: photoevaporati…
Using EUV driven external photoevaporation to test viscous evolution of protoplanetary discs
Giulia Ballabio, James E. Owen
Protoplanetary discs are thought to evolve either through angular momentum transport driven by viscous processes or through angular momentum removal induced by magnetohydrodynamic…
Wind-AE: A Fast, Open-source 1D Photoevaporation Code with Metal and Multi-frequency X-ray Capabilities
Madelyn Broome, Ruth Murray-Clay, John McCann +1
Throughout their lives, short period exoplanets (<100 days) experience X-ray and extreme-UV (XUV) stellar irradiation that can heat and photoionize planets' upper atmospheres, driv…
The effect of radiation pressure on the dispersal of photoevaporating discs
Alfie Robinson, James E. Owen, Richard A. Booth
Observed IR excesses indicate that protoplanetary discs evolve slowly for the majority of their lifetime before losing their near- and mid-IR excesses on short timescales. Photoeva…
