Probing the Disk Structure of PDS 66, an Aged Classical T Tauri Star
Abstract
We combine our new millimeter interferometry data from the Australia Telescope Compact Array with existing data for the old ( 17Myr), nearby (86pc) classical T Tauri star, PDS 66. This extensive data set will be used to constrain physical models of the spectral energy distribution using the CGPLUS code described by Dullemond et al., 2001. The limited range of parameters will describe the structure of the circumstellar disk, and lead us to a better understanding of grain growth, possibility of planet formation, and disk evolution in general. Our goals are (1) to determine the grain size inferred from our millimeter observations, (2) to determine whether the data can be modeled with a fully flared disk, and (3) to constrain specific disk parameters such as the inner and outer disk radius, and surface density. We find evidence of grain growth from a preliminary analysis of the mm-wave data. This project is part of the Spitzer Legacy Program `Formation and Evolution of Planetary Systems’ (FEPS).
