Physics

Scientific paper

We conducted a parameter study based on simulated annealing to construct a self-consistent model of HH30's circumstellar disk using all available observations in the wavelength domain 1μm. . . 3mm. Recently made high-resolution observations of continuum visibilities at = 1.3mm with the Plateau de Bure Interferometer [1] and the spectral energy distribution (SED) in the mid infrared with IRS on the Spitzer Space Telescope (SST) [2] significantly increased constraints on our modeling attempt. We present models of the edge-on disk featuring an inner depletion zone with 100AU diameter explaining subsets of the available data and conclude the presence of dust growth and settling.
