The last 10 years have brought spectacular images of discs around young stars. One of the main things we have learnt is that planet formation takes place already during the 'violent' phase of star formation, where interactions with other stars are important. This can help shed light on old mysteries in disc evolution, such as how accretion bursts and dust melting events may be triggered by...
The process of star formation frequently produces multi-star systems, with nearly half of Sun-like stars formed as part of a pair. Protoplanetary disks in these systems experience additional gravitational interactions and are subject to environments unlike those around single stars, influencing their evolution and subsequent planet formation. We investigate a potential source of variability in...
In recent years, many wide orbit circumbinary giant planets have been discovered. These may have formed by gravitational fragmentation of circumbinary disks. The aim of this work is to investigate the lower limit of circumbinary disc fragmentation and to compare it to the lower limit of circumstellar disc fragmentation. Using the smoothed particle hydrodynamics code SEREN with the Lombardi...
Most of young stars are part of multiple stellar systems, where star-disc interactions shape protoplanetary disc and impact the planet formation processes. In particular, tidal perturbations from companion stars imprint high dust velocity dispersion, hindering dust particle growth. However the formation of substructures, like spiral arms or horseshoes, leads to the creation of regions of high...
Binaries carve unique inner cavities into their young surrounding protoplanetary disc. These cavities can be as large and eccentric like GG Tau A. However, with recent observation around tighter binaries like CsCha reveal circular, smaller cavities when compared to the separation of the binary stars. Since similar dynamics carves these cavities, what are we missing when to understand the...
