SEDust fits AGB star SEDs with DUSTY (ascl:9911.001) models to derive luminosity and mass-loss rates. The pipeline estimates luminosities, optical depths, and mass-loss rates for AGB and LPV stars, based on multi-band photometric data, and fits observed stellar photometry with a pre-computed grid of DUSTY models. It handles both carbon-rich and oxygen-rich stars and returns best-fit SEDs, luminosities, and mass-loss rates. The SEDust pipeline automates the fitting process, removing the need for manual trial-and-error adjustments.
