Exploring Planet Formation around Host Stars of Different Masses

Context: Planetary and stellar formation are inherently linked: the physical and chemical compositions of stellar birth environments – the natal protoplanetary disks – are responsible for the resultant planetary conditions.

Aims: Aims: To examine how stellar hosts and their surrounding protoplanetary disks affect the formation and migration of planets. 

Methodology:  Adapting and utilising the code developed in (Liu et al. 2019), and expanding on the findings to include host stars in the range of 1-3M☉and investigate the impact that different conditions – e.g. disk size, accretion rate, and migration – have on planetary growth.

Results: There is a clear correlation between giant planet growth and planetary migration.  Gas accretion of the protoplanet is more challenging when the mass of the host star is increased. 

Conclusions & Future Work: The simulations will be compares to current observational findings around solar/intermediate-mass stars and develop some analysis to quantify an observational marker to determine whether a planet formed in situ or experienced type I/II migration.
