Photoevaporation obfuscates the distinction between wind and viscous angular momentum transport in protoplanetary discs
Gavin A. L. Coleman, Joseph K. Mroueh, Thomas J. Haworth
How protoplanetary discs evolve remains an unanswered question. Competing theories of viscosity and magnetohydrodynamic disc winds have been put forward as the drivers of angular m…
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…
Illuminating evaporating protostellar outflows: ERIS/SPIFFIER reveals the dissociation and ionization of HH 900
Megan Reiter, Thomas J. Haworth, Carlo F. Manara +4
Protostellar jets and outflows are signposts of active star formation. In H II regions, molecular tracers like CO only reveal embedded portions of the outflow. Outside the natal cl…
XUE. Molecular inventory in the inner region of an extremely irradiated Protoplanetary Disk
María Claudia Ramirez-Tannus, Arjan Bik, Lars Cuijpers +24
We present the first results of the eXtreme UV Environments (XUE) James Webb Space Telescope (JWST) program, that focuses on the characterization of planet forming disks in massive…
FRIED v2. A new grid of mass loss rates for externally irradiated protoplanetary discs
Thomas J. Haworth, Gavin A. L. Coleman, Lin Qiao +2
We present a new FRIED grid of mass loss rates for externally far-ultraviolet (FUV) irradiated protoplanetary discs. As a precursor to the new grid, we also explore the microphysic…
The VLT MUSE NFM view of outflows and externally photoevaporating discs near the Orion Bar
Thomas J. Haworth, Megan Reiter, C. Robert O'Dell +10
We present VLT/MUSE Narrow Field Mode (NFM) observations of a pair of disc-bearing young stellar objects towards the Orion Bar: 203-504 and 203-506. Both of these discs are subject…
Isolating Dust and Free-Free Emission in ONC Proplyds with ALMA Band 3 Observations
Nicholas P. Ballering, L. Ilsedore Cleeves, Thomas J. Haworth +6
The Orion Nebula Cluster (ONC) hosts protoplanetary disks experiencing external photoevaporation by the cluster's intense UV field. These ``proplyds" are comprised of a disk surrou…
Planet formation via pebble accretion in externally photoevaporating discs
Lin Qiao, Gavin A. L. Coleman, Thomas J. Haworth
We demonstrate that planet formation via pebble accretion is sensitive to external photoevaporation of the outer disc. In pebble accretion, planets grow by accreting from a flux of…
