Abstract
While existing Spitzer observations of debris disks show a wide range of diversity in disk morphologies and spectral energy distributions (SEDs), the majority of debris disks are not resolved, resulting in very few direct constrains on disk structures and properties. Progress in high fidelity reductions and an improved understanding of the Spitzer Point Spread Functions have enable us to resolved many more nearby systems at 24 and/or 70 micron. A better reconstruction of the disk structures can be drawn by combining detailed SEDs, composed of Spitzer broad-band (MIPS 24 and 70 micron) photometry and spectroscopy (IRS and MIPS-SED), and resolved imaging. I will present the detailed models of these newly resolved systems to study the diversity of debris disks.
