cds-question@unistra.frmagellanic-cloudsinfrared-photometryBy analyzing the spectral energy distributions (SEDs) of resolved stars in nearby galaxies, we can constrain their stellar properties and line-of-sight dust extinction. From the Scylla survey, we obtain ultraviolet to near-infrared photometry from Wide Field Camera 3 on board the Hubble Space Telescope for more than 1.5 million stars in the SMC and LMC. We use the Bayesian Extinction and Stellar Tool (BEAST) to analyze the multiband SEDs of these sources and characterize their initial masses, ages, metallicities, distances, and line-of-sight extinction properties (e.g., AV, RV). We apply quality cuts and perform validation simulations to construct a catalog of over 550000 stars with high-reliability SED fits, which we use to analyze the stellar content and extinction properties of the SMC and LMC. We detect stars with masses as low as 0.6M_{sun}_. BEAST stellar age distributions show a jump in observed stars around 6Gyr ago, which agrees with star formation histories. Extinctions (AV) in both galaxies follow a log-normal distribution. We compare AV with ancillary gas and dust tracers like HI, Halpha, and far-infrared (FIR) dust emission and find positive correlations on a field-by-field basis. We convert observed AV to predicted dust surface densities using the Draine et al. model and find AV-based dust surface densities are a factor of ~2.5 lower than observed FIR-based dust surface densities, a correction factor similar to other studies.2025ApJ...982...33Lhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/ApJ/982/33CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toJ/ApJ/871/151 : METAL Hubble program.
