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…
