Young stellar objects
Alicia Aarnio aims to understand the innermost regions of disks around young, intermediate mass stars: inner disk structure; geometry; and how material is moving within and out of the star-disk system. She is looking at Herbig AeBe stars and their circumstellar disks to see how their accretion and outflow properties relate to the properties of the star and its disk. Aarnio is using Magellan data to determine properties of winds and accretion flows via the spectral lines these processes create, and she is comparing these data to interferometric results, which give inner disk properties. With radiative transfer models, Aarnio hopes to bring these data sets together to establish a picture of how energy and mass are being transported within these systems.
