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 …

The birth environment of planetary systems

RJ Parker - Royal Society Open Science, 2020 - royalsocietypublishing.org
Star and planet formation are inextricably linked. In the earliest phases of the collapse of a
protostar, a disc forms around the young star and such discs are observed for the first …

Protoplanetary disc truncation mechanisms in stellar clusters: comparing external photoevaporation and tidal encounters

AJ Winter, CJ Clarke, G Rosotti, J Ih… - Monthly Notices of …, 2018 - academic.oup.com
Most stars form and spend their early life in regions of enhanced stellar density. Therefore,
the evolution of protoplanetary discs (PPDs) hosted by such stars are subject to the …

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 …

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 …

The FRIED grid of mass-loss rates for externally irradiated protoplanetary discs

TJ Haworth, CJ Clarke, W Rahman… - Monthly Notices of …, 2018 - academic.oup.com
We present an open access grid of 3930 calculations of externally evaporating
protoplanetary discs. This spans a range of disc sizes (1–400 au), disc masses, UV field …

The evolution of dust in discs influenced by external photoevaporation

AD Sellek, RA Booth, CJ Clarke - Monthly Notices of the Royal …, 2020 - academic.oup.com
Protoplanetary discs form and evolve in a wide variety of stellar environments and are
accordingly exposed to a wide range of ambient far-ultraviolet (FUV) field strengths. Strong …

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 …

The evolution of protoplanetary discs in star formation and feedback simulations

L Qiao, TJ Haworth, AD Sellek… - Monthly Notices of the …, 2022 - academic.oup.com
We couple star cluster formation and feedback simulations of a Carina-like star-forming
region with 1D disc evolutionary models to study the impact of external photoevaporation on …

External photoevaporation of circumstellar discs constrains the time-scale for planet formation

F Concha-Ramírez, MJC Wilhelm… - Monthly Notices of …, 2019 - academic.oup.com
Planet-forming circumstellar discs are a fundamental part of the star formation process.
Since stars form in a hierarchical fashion in groups of up to hundreds or thousands, the UV …
