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, Hilke E. Schlichting +1
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…
High-resolution [OI] line spectral mapping of TW Hya consistent with X-ray driven photoevaporation
Ch. Rab, M. Weber, G. Picogna +2
Theoretical models indicate that photoevaporative and magnetothermal winds play a crucial role in the evolution and dispersal of protoplanetary disks and affect the formation of pl…
Accreting Transition Discs with large cavities created by X-ray photoevaporation in C and O depleted discs
Barbara Ercolano, Michael L. Weber, James E. Owen
Circumstellar discs with large dust depleted cavities and vigorous accretion onto the central star are often considered signposts for (multiple) giant planet formation. In this let…
The Mdot - M* relation of pre-main sequence stars: a consequence of X-ray driven disc evolution
B. Ercolano, D. Mayr, J. E. Owen +2
We analyse current measurements of accretion rates onto pre-main sequence stars as a function of stellar mass, and conclude that the steep dependance of accretion rates on stellar…
The Photoevaporative Wind from the Disk of TW Hya
I. Pascucci, M. Sterzik, R. D. Alexander +6
Photoevaporation driven by the central star is expected to be a ubiquitous and important mechanism to disperse the circumstellar dust and gas from which planets form. Here, we pres…
Radiation-Hydrodynamic Models of X-Ray & EUV Photoevaporating Protoplanetary Discs
J. E. Owen, B. Ercolano, C. J. Clarke +1
(Abridged) We present the first radiation-hydrodynamic model of a protoplanetary disc irradiated with an X-EUV spectrum. In a model where the total ionizing luminosity is divided e…
