From dust to planets -- II. Effects of wide binary companions and external photoevaporation on planetesimal and embryo formation
Gavin A. L. Coleman
More than half of Solar-type stars are found in binary systems. The numbers of exoplanets within binary systems in s-type orbits now numbers over 700. However, whilst the numbers h…
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…
How the gradient of versus UV field strength yields insights into the ages of protoplanetary disc populations
Gavin A. L. Coleman, Sierk E. van Terwisga
FUV radiation from massive stars launch photoevaporative winds from the outer regions of protoplanetary discs around other stars, removing gas and dust. Observations have identifie…
Runaway origins of a disc mass gradient in Orionis
Gavin A. L. Coleman, Thomas J. Haworth, Jinyoung Serena Kim
Radiation from massive stars is known to significantly affect the evolution of protoplanetary discs around surrounding stars by driving external photoevaporative winds. Typically m…
Solar C/O ratio in planet-forming gas at 1 au in a highly irradiated disk
Ilane Schroetter, Olivier Berné, Emeric Bron +18
The chemical composition of exoplanets is thought to be influenced by the composition of the disks in which they form. JWST observations have unveiled a variety of species in numer…
