A parametric model for externally irradiated protoplanetary disks with photoevaporative winds
Luke Keyte, Thomas J. Haworth
Protoplanetary disks in massive star-forming regions may be exposed to ultraviolet radiation fields orders of magnitude stronger than the interstellar background. This intense radi…
Formation of multi-planetary systems via pebble accretion in externally photoevaporating discs in stellar clusters
Lin Qiao, Gavin A. L. Coleman, Thomas J. Haworth
In this paper, we investigate how external photo-evaporation influences the formation, dynamical evolution and the resultant planetary architecture of multi-planet systems born in…
Using simultaneous mass accretion and external photoevaporation rates for d203-504 to constrain disc evolution processes
Gavin A. L. Coleman, Thomas J. Haworth, Ilane Schroetter +1
We cannot understand planet formation without understanding disc evolutionary processes. However, there is currently ambiguity about how protoplanetary discs transport angular mome…
Investigating dusty Red Supergiant outflows in Westerlund 1 with 3D Hydrodynamic simulations
C. J. K. Larkin, J. Mackey, T. J. Haworth +1
Recent JWST observations towards Westerlund 1 revealed extensive nebular emission associated with the cluster. Given the age of the region and proximity of that material to massive…
XUE. JWST spectroscopy of externally irradiated disks around young intermediate-mass stars
MarÃa Claudia RamÃrez-Tannus, Arjan Bik, Konstantin V. Getman +17
Most young stars and therefore planetary systems form in high-mass star forming regions and are exposed to ultraviolet radiation, affecting the protoplanetary disk. These regions a…
Line ratio identification of external photoevaporation
Tyger Peake, Thomas J. Haworth, Mari-Liis Aru +1
External photoevaporation of protoplanetary discs, by massive O stars in stellar clusters, is thought to be a significant process in the evolution of a disc. It has been shown to r…
