Astronomy Colloquium
"3-D Dust Radiation Transfer: What can it do for you?"
Date: Thursday, September 9th
Time: 3:30 pm
Place: 4421 Sterling Hall Same Location
Speaker: Barbara Whitney, UW SAL Department
Abstract: I will introduce myself to the department by describing some applications of our radiation transfer codes to the study of star formation on size scales small and large. The codes calculate dust thermal and non-thermal emission, scattering, and polarization in arbitrary 3-D geometries. I will discuss how we can map the structure of the inner disks of T Tauri stars by modeling their optical and infrared variability; our models of Young Stellar Objects (protostars and their circumstellar disks and envelopes) and star forming regions; comparison of a Galactic population synthesis model of YSOs to GLIMPSE catalogs to determine the star formation rate of our Galaxy; determining the star formation rate of the Large Magellanic by counting and modeling YSOs; and galaxy models incorporating stars, YSOs, and interstellar dust, including PAHs. As I dip my toes into the field of extragalactic research, I will be interested to get feedback on whether these codes, which are publicly available, can be useful to you in your research, and what additional development is most desirable (e.g., line emission).
