Project description
Modelling planet nurseries could help us understand the origin of our solar system
Shortly after their birth, almost all low-mass stars are surrounded by flattened, rotating disks of cool gas and dust. These protoplanetary disks can persist for several million years, during which some material accretes onto the star, some is lost through outflows and some condenses into the tiny beginnings of future planets. Understanding these processes in protoplanetary disks is fundamental to our understanding of the origin of planetary systems, and magnetism likely plays a significant role. The EU-funded InAndOut project is developing a computational model of infall, accretion and outflows during the early phases of star and disk formation that incorporates small-scale effects while accounting for the magnetic field structure of the protostellar environment. Model outputs could help us understand the origin of our own solar system and the continuous evolution of our universe.
Objective
Modelling the interplay of infall, accretion, and outflows during the early phases of star and disk formation is the key to understanding the origin of planetary systems. So-called protoplanetary disks form shortly after the birth of a star, and, as ultimately revealed by recent discoveries , disks are the nurseries of planets. My project, 'InAndOut: Towards a complete understanding of young embedded discs', tackles this issue by applying novel computational tools to investigate the small-scale effects in disks, while consistently accounting for the properties provided by the protostellar environment. Adopting ten prestellar cores located in different environments of a parental filamentary Giant Molecular Cloud, I will simulate the formation and evolution of embedded disk state-of-the-art code framework DISPATCH. To account for the observed diversity of cosmic-ray ionisation rates among different prestellar cores, I will vary the cosmic ray ionisation rate in my models. To guarantee a valid comparison of my results with cutting-edge observations, I will produce synthetic observations with the radiative transfer code POLARIS. Synthetic maps of dust polarisation can be used to get a better understanding of the magnetic field structure on scales beyond the disk. Anticipating first ALMA results of circular polarisation due to Zeeman splitting in young disks in the near future, it is timely to provide synthetic maps of circular polarisation, as they can tell us about the magnetic field strength in disks. Following the trajectory of the dust and gas particles in embedded disks from infall, through the disk to outflows will allow me to study, whether dust and gas can return into the disk after being ejected by a wind. Finding an answer to this question has important implications for our understanding of the origin of our solar system. Moreover, I will identify chemical tracers for the kinematics such as infall and outflow involved in the embedded disk phase.
