The fundamentals of Lyman-alpha exoplanet transits
James E. Owen, Ruth A. Murray-Clay, Ethan Schreyer +7
Lyman- transits have been detected from several nearby exoplanets and are one of our best insights into the atmospheric escape process. However, due to ISM absorption, we typica…
A slim disc approach to external photoevaporation of discs
James E Owen, Noumahn Altaf
The photoevaporation of protoplanetary discs by nearby massive stars present in their birth cluster plays a vital role in their evolution. Previous modelling assumes that the disc…
Exoplanet atmosphere evolution: emulation with neural networks
James G. Rogers, Clàudia Janó Muñoz, James E. Owen +1
Atmospheric mass-loss is known to play a leading role in sculpting the demographics of small, close-in exoplanets. Knowledge of how such planets evolve allows one to ``rewind the c…
TESS Hunt for Young and Maturing Exoplanets (THYME) VI: an 11 Myr giant planet transiting a very low-mass star in Lower Centaurus Crux
Andrew W. Mann, Mackenna L. Wood, Stephen P. Schmidt +48
Mature super-Earths and sub-Neptunes are predicted to be Jovian radius when younger than 10 Myr. Thus, we expect to find 5-15 planets around young stars even if t…
MRI-active inner regions of protoplanetary discs. II. Dependence on dust, disc and stellar parameters
Marija R. Jankovic, Subhanjoy Mohanty, James E. Owen +1
Close-in super-Earths are the most abundant exoplanets known. It has been hypothesized that they form in the inner regions of protoplanetary discs, out of the dust that may accumul…
Photoevaporation vs. core-powered mass-loss: model comparison with the 3D radius gap
James G. Rogers, Akash Gupta, James E. Owen +1
The EUV/X-ray photoevaporation and core-powered mass-loss models are both capable of reproducing the bimodality in the sizes of small, close-in exoplanets observed by the \textit{K…
