XUE. ProDiMo models of internally and externally irradiated planet-forming disks around 0.3-4.0 solar mass stars (The IRIS project I)
Jenny Frediani, Konstantin V. Getman, Peter Woitke +18
Most stars and planets form in massive star-forming regions, where disks are exposed to external far-ultraviolet (FUV) radiation from nearby O- and B-type stars. The combined effec…
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…
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…
XUE. JWST spectroscopy of externally irradiated disks around young intermediate-mass stars
María Claudia Ramírez-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…
A Particle-based Approach to Dust Dynamics in External Photoevaporative Winds
S. Paine, T. J. Haworth, R. P. Nelson
Planet-forming discs in sufficiently strong UV environments lose gas in external photoevaporative winds. Dust can also be entrained within these winds, which has consequences for t…
How the microphysical properties of external photoevaporation influence the global evolution of protoplanetary discs
Gavin A. L. Coleman, Thomas J. Haworth, Lin Qiao
External photoevaporation is one of the dominant mechanisms for mass loss from protoplanetary discs. However this mass loss is theoretically expected to depend upon the microphysic…
XUE. Thermochemical Modeling Suggests a Compact and Gas-Depleted Structure for a Distant, Irradiated Protoplanetary Disk
Bayron Portilla-Revelo, Konstantin V. Getman, María Claudia Ramírez-Tannus +14
Unveiling the physical structure of protoplanetary disk is crucial for interpreting the diversity of the exoplanet population. Until recently, the census of the physical properties…
Discovery of Radio Recombination Lines from Proplyds in the Orion Nebula Cluster
Ryan D. Boyden, Kimberly L. Emig, Nicholas P. Ballering +5
We present new Atacama Large Millimeter/submillimeter Array observations that, for the first time, detect hydrogen and helium radio recombination lines from a protoplanetary disk.…
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…
A possible trail of dust from a young, highly-extincted brown dwarf in the outskirts of the Trapezium Cluster
Thomas J. Haworth, Mark J. McCaughrean, Samuel G. Pearson +1
We present the JWST discovery of a highly-extincted () candidate brown dwarf (M) in the outskirts of the Trapezium Cluster that appears to be coincide…
The past, present and future of observations of externally irradiated disks
Planet formation environments collaboration, Megan Allen, Rossella Anania +51
Recent years have seen a surge of interest in the community studying the effect of ultraviolet radiation environment, predominantly set by OB stars, on protoplanetary disc evolutio…
Impact of photoevaporative winds in chemical models of externally irradiated protoplanetary disks
Luke Keyte, Thomas J. Haworth
Most stars form in dense clusters within high-mass star-forming regions, where protoplanetary disks may be exposed to intense UV radiation from nearby massive stars. While previous…
Thermal emission from bow shocks. III. Variable diffuse X-ray emission from stellar-wind bow shocks driven by dynamical instabilities
Jonathan Mackey, Arun Mathew, Ahmad A. Ali +5
X-ray emission from wind-driven bow shocks is both difficult to measure and predict, but may give important insights into the energy budget of the hot phase of the ISM by quantifyi…
A New Look at Disk Winds and External Photoevaporation in the -Orionis Cluster
K. Maucó, C. F. Manara, A. Bayo +12
Disk winds play a crucial role in the evolution of protoplanetary disks. Typical conditions for star and planet formation are in regions with intermediate or strong UV radiation fi…
A tell-tale tracer for externally irradiated protoplanetary disks: comparing the [CI] 8727 A line and ALMA observations in proplyds
Mari-Liis Aru, Karina Mauco, Carlo F. Manara +15
The evolution of protoplanetary disks in regions with massive OB stars is influenced by externally driven winds that deplete the outer parts of disks. These winds have previously b…
A multi-ion non-equilibrium solver for ionised astrophysical plasmas with arbitrary elemental abundances
Arun Mathew, Jonathan Mackey, Maggie Celeste +2
While many astrophysical plasmas can be modelled successfully assuming ionisation and thermal equilibrium, in some cases this is not appropriate and a non-equilibrium approach is r…
Kaleidoscope of irradiated disks: MUSE observations of proplyds in the Orion Nebula Cluster. I. Sample presentation and ionization front sizes
Mari-Liis Aru, Karina Mauco, Carlo F. Manara +10
In the Orion Nebula Cluster (ONC), protoplanetary disks exhibit ionized gas clouds in the form of a striking teardrop shape as massive stars irradiate the disk material. We present…
A far-ultraviolet-driven photoevaporation flow observed in a protoplanetary disk
Olivier Berné, Emilie Habart, Els Peeters +143
Most low-mass stars form in stellar clusters that also contain massive stars, which are sources of far-ultraviolet (FUV) radiation. Theoretical models predict that this FUV radiati…
Photoevaporation obfuscates the distinction between wind and viscous angular momentum transport in protoplanetary discs
Gavin A. L. Coleman, Joseph K. Mroueh, Thomas J. Haworth

The external photoevaporation of structured protoplanetary disks
Matías Gárate, Paola Pinilla, Thomas J. Haworth +1
The dust in planet-forming disks evolve rapidly through growth and radial drift, and external photoevaporation also contributes to this evolution in massive star-forming regions. W…
