Comparing real and synthetic observations of protostellar disks

Zamponi, Joaquin (2023): Comparing real and synthetic observations of protostellar disks. Dissertation, LMU München: Fakultät für Physik

Abstract

Nascent envelope disk structures around protostars play a crucial role in the process of star and planet formation. As ALMA reveals unprecedented details of the envelope, disk, and outflow structures in nearby protostellar systems, a consistent interpretation for these observations remains absent, instead, highly simplified models are often adopted to partially fit the observed features. In this project, we aim to generate more realistic synthetic observations of the nascent protostellar disk and envelope system, using existing radiation and non-ideal magnetohydrodynamic simulations of protostellar collapse and disk formation. The main goal of the project is to provide multi-facet interpretation of the current continuum and polarization observations of protostellar sources at their earliest stages, and offer more realistic constraints on the dust growth in the early protoplanetary disks.
