The dispersal of compact protoplanetary discs

Giovanni Picogna, Barbara Ercolano

Compact protoplanetary discs are becoming increasingly prominent in observations. Their dispersal pathways may differ substantially from those of extended discs. We aim to quantify…

Can photoevaporation open gaps in protoplanetary discs?

Michael L. Weber, Barbara Ercolano, Giovanni Picogna

We investigate whether photoevaporation alone can open and sustain gaps in protoplanetary discs by coupling the evolving disc structure with the photoevaporative flow in two dimens…

Global Hall-magnetohydrodynamic simulations of transition disks

Eleftheria Sarafidou, Oliver Gressel, Barbara Ercolano

Context. Transition disks (TDs) are a type of protoplanetary disk characterized by a central dust and gas cavity. The processes behind how these cavities are formed and maintained,…

Photoevaporation of protoplanetary discs with PLUTO+PRIZMO I. Lower X-ray-driven mass-loss rates due to enhanced cooling

Andrew D. Sellek, Tommaso Grassi, Giovanni Picogna +3

Context: Photoevaporation is an important process for protoplanetary disc dispersal but there has so far been a lack of consensus from simulations over the mass-loss rates and the…

Approximating Rayleigh Scattering in Exoplanetary Atmospheres using Physics-informed Neural Networks (PINNs)

David Dahlbüdding, Karan Molaverdikhani, Barbara Ercolano +1

This research introduces an innovative application of physics-informed neural networks (PINNs) to tackle the intricate challenges of radiative transfer (RT) modeling in exoplanetar…

The interplay between forming planets and photoevaporating discs II: Wind-driven gas redistribution

Michael L. Weber, Giovanni Picogna, Barbara Ercolano

Disc winds and planet-disc interactions are two crucial mechanisms that define the structure, evolution and dispersal of protoplanetary discs. While winds are capable of removing m…
