Abstract

Using data from the Atacama Large Millimeter Array (ALMA) telescope, I plan create a model of the Class 0 protostar L1527-IRS (hereby referred to as L1527) that matches measured Spectral Energy Distributions (SED’s) as well as a realistic physical structure. Due to its ability to measure in far-infrared wavelengths, ALMA data represents a significant jump in reach and accuracy when observing protostars. New data for L1527 shows discrepancies with the currently accepted model(s) of the protostar. At the conclusion of this product, I plan to have a model of L1527 that accurately represents the measured spectral energy distribution as well as a plausible physical structure. I am primarily using HOCHUNK3D, a set of codes designed by Dr. Barbara Whitney to create and examine protostar models. Currently I am working with models which fit measured energy distributions but contain problematic physical features, namely interference between the envelope and the outflow cavities.
