Protoplanetary disc evolution and dispersal
In this thesis I have studied how discs around young stars evolve and disperse. In particular, I build models which combine viscous evolution with photoevaporation, as previous work suggests that photoevaporation can reproduce the observed disc evolution and dispersal time-scales. The main question …

ASSESSING THE ROLE OF EXTERNAL PHOTOEVAPORATION OF PROTOPLANETARY DISCS IN NEARBY STAR-FORMING REGIONS
Characterising the physical processes driving protoplanetary disc evolution and the connection to the star-forming environment is essential to understanding planet formation and diversity. Most stars (and their discs) in the Galaxy form in massive clusters where the intense UV radiation emitted by …

A Global Hydrodynamic Investigation into the Transport of Material in Protoplanetary Discs
… enables the formation of massive planets within disc lifetimes, addressing a key challenge in traditional core accretion scenarios. Our study investigates the influence of massive planets on gas and dust motion in protoplanetary discs, with a focus on material transport through planetary- induced …

Magnetic Fields in Protoplanetary Discs
Protoplanetary discs are flattened discs of gas and dust surrounding young stars that are believed to be the sites of planet formation. They are believed to be threaded by large-scale magnetic fields, which significantly affect their dynamics through processes such as the magneto-rotational …

Connecting models and observations of disc evolution and planet formation
… and composition from gas- and dust-rich discs orbiting young stars. Over the last decade, the Atacama Large Millimeter/submillimeter Array revolutionised our understanding of planet formation, opening up the possibility of determining the physical-chemical properties of protoplanetary …
