The external photoevaporation of planet-forming discs

AJ Winter, TJ Haworth - The European Physical Journal Plus, 2022 - Springer
Planet-forming disc evolution is not independent of the star formation and feedback process
in giant molecular clouds. In particular, OB stars emit UV radiation that heats and disperses …

Dynamics of young stellar clusters as planet-forming environments

M Reiter, RJ Parker - The European Physical Journal Plus, 2022 - epjplus.epj.org
Most stars and thus most planetary systems do not form in isolation. The larger star-forming
environment affects protoplanetary disks in multiple ways: Gravitational interactions with …

fried v2: a new grid of mass-loss rates for externally irradiated protoplanetary discs

TJ Haworth, GAL Coleman, L Qiao… - Monthly Notices of …, 2023 - academic.oup.com
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 microphysics of …

Planet formation via pebble accretion in externally photoevaporating discs

L Qiao, GAL Coleman, TJ Haworth - Monthly Notices of the …, 2023 - academic.oup.com
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 …

Toward a population synthesis of disks and planets-II. Confronting disk models and observations at the population level

A Emsenhuber, R Burn, J Weder, K Monsch… - Astronomy & …, 2023 - aanda.org
Aims. We want to find the distribution of initial conditions that best reproduces disc
observations at the population level. Methods. We first ran a parameter study using a 1D …

Dispersal of protoplanetary discs: how stellar properties and the local environment determine the pathway of evolution

GAL Coleman, TJ Haworth - Monthly Notices of the Royal …, 2022 - academic.oup.com
We study the evolution and final dispersal of protoplanetary discs that evolve under the
action of internal and external photoevaporation, and different degrees of viscous transport …

Radiation shielding of protoplanetary discs in young star-forming regions

MJC Wilhelm, S Portegies Zwart… - Monthly Notices of …, 2023 - academic.oup.com
Protoplanetary discs spend their lives in the dense environment of a star-forming region.
While there, they can be affected by nearby stars through external photoevaporation and …

Deep diving off the 'Cosmic Cliffs': previously hidden outflows in NGC 3324 revealed by JWST

M Reiter, JA Morse, N Smith, TJ Haworth… - Monthly Notices of …, 2022 - academic.oup.com
We present a detailed analysis of the protostellar outflow activity in the massive star-forming
region NGC 3324, as revealed by new Early Release Observations (EROs) from the James …

The growth and migration of massive planets under the influence of external photoevaporation

AJ Winter, TJ Haworth, GAL Coleman… - Monthly Notices of the …, 2022 - academic.oup.com
The formation of gas giant planets must occur during the first few Myr of a star's lifetime,
when the protoplanetary disc still contains sufficient gas to be accreted on to the planetary …

Chemical Modeling of Orion Nebula Cluster Disks: Evidence for Massive, Compact Gas Disks with Interstellar Gas-to-dust Ratios

RD Boyden, JA Eisner - The Astrophysical Journal, 2023 - iopscience.iop.org
The stellar cluster environment is expected to play a central role in the evolution of
circumstellar disks. We use thermochemical modeling to constrain the dust and gas masses …
