High-resolution studies of exoplanetesimal belt formation and evolution
… the protoplanetary system: planets, and belts of planetesimals (km-sized rocky and icy bodies). Planetesimals within belts readily collide and produce detectable levels of dust and gas, known as debris discs, around 20% of main sequence stars. Despite the ubiquity of planets and planetesimal belt …

The structure and stability of vortices in astrophysical discs
… a barrier to their potential as sites for planetesimal formation. It is challenging to build planetesimals from dust within the lifetime of a protoplanetary disc and before such bodies spiral into the central star. Collecting matter in vortices is a promising mechanism for planetesimal …

The origin and evolution of Transneptunian binaries
… Understanding what mechanisms have lead to the formation of such a high binary fraction, and their orbital distributions, holds the potential to elucidate the processes of planetesimal formation and evolution in general. Previous work has shown that gravitational instability is an efficient …
