ASSESSING THE ROLE OF EXTERNAL PHOTOEVAPORATION OF PROTOPLANETARY DISCS IN NEARBY STAR-FORMING REGIONS
… This causes outside-in disc depletion throughout external photoevaporation. In this thesis, I investigate how external photoevaporation shapes disc dynamics across a broad range of far-ultraviolet (FUV) radiation fields, focusing on nearby star-forming regions within 500 pc. Using numerical disc …

The influence of stellar birth environment on protoplanetary disc dispersal
… are tidal truncation by star-disc encounters and external photoevaporation due to irradiation by massive stars. I make the distinction between encounters that occur in multiple systems and those that occur between individual stars (type I and type II encounters). I model the specific case of HV …

The impact of environment on the evolution of protoplanetary discs
… discs are star-disc encounters, and external photoevaporation. In this thesis, I show that sub-mm observations of the RW Aur system are well described by an ongoing tidal encounter between the circumprimary disc and the secondary star. This makes RW Aur the only system known to date …

The impact of star cluster environments on planet formation
… calculations of mass-loss in discs due to external photoevaporation severely overestimate the detrimental effects of EUV and FUV radiation. By calculating the UV background field in star-forming regions, I find that the initial spatial distribution of stars greatly affects the amount of UV …
