April 2022: Did Earth eat its leftovers? – Carter & Stewart (2022)
In this paper, published in The Planetary Science Journal, we
investigate the provenances of planetesimals 'leftover' in the inner disk in the late stages of accretion simulations.

April 2022: Denman et al. (2022) – Atmosphere loss in oblique Super-Earth collisions
In this work by Denman et al. we modelled
the loss of atmosphere in oblique collisions between super-Earth
sized planets. We show that oblique collisions are less efficient
at atmosphere removal than head-on collisions. We found that a single
collision cannot remove all the atmosphere
without also removing a significant fraction of the mantle.
Read the paper in MNRAS.
January 2022: Congratulations Dr Denman!
Dr Thomas Denman passed his viva in November and has now been awarded his PhD!

August 2020: Colliding in the shadows of giants – Carter & Stewart (2020)
In this paper, available on arXiv
and soon to be published in The Planetary Science Journal, we
investigate planetesimal–planetesimal collisions during the growth
and migration of giant planets. Gas giant migration induces large
numbers of high velocity collisions between planetesimals, many of
which can cause shock-vaporization of planetesimal materials.
June 2020: Denman et al. (2020) – Atmosphere loss in planet–planet collisions
Thomas Denman, a grad student at the University of Bristol I co-advise,
had his first first-author paper published! In this work we modeled
the loss of atmosphere in collisions between mini-Neptune and super-Earth
sized planets. We found that a single collision cannot remove all the atmosphere
without also removing a significant fraction of the mantle.
