ADC_Keywords: Photometry, infrared Keywords: galaxies: stellar content ; infrared: stars ; Local Group ; Magellanic Clouds Abstract: The Mid-Infrared Instrument (MIRI) for the James Webb Space Telescope (JWST) will revolutionize our understanding of infrared stellar populations in the Local Volume. Using the rich Spitzer-IRS spectroscopic data set and spectral classifications from the Surveying the Agents of Galaxy Evolution (SAGE)-Spectroscopic survey of more than 1000 objects in the Magellanic Clouds, the Grid of Red Supergiant and Asymptotic Giant Branch Star Model (GRAMS; Sargent+ 2011ApJ...728...93S and Srinivasan+ 2011, J/A+A/532/A54), and the grid of YSO models by Robitaille+ (2006ApJS..167..256R), we calculate the expected flux densities and colors in the MIRI broadband filters for prominent infrared stellar populations. We use these fluxes to explore the JWST/MIRI colors and magnitudes for composite stellar population studies of Local Volume galaxies. MIRI color classification schemes are presented; these diagrams provide a powerful means of identifying young stellar objects, evolved stars, and extragalactic background galaxies in Local Volume galaxies with a high degree of confidence. Finally, we examine which filter combinations are best for selecting populations of sources based on their JWST colors. Description: In order to predict fluxes and colors through the James Webb Space Telescope (JWST) Mid-Infrared Instrument (MIRI) filters, we have made use of Spitzer-IRS spectra, from the SAGE-Spec legacy survey of the LMC (Kemper+ 2010, J/PASP/122/683). The IRS spectra cover a wavelength range from 5.3 to 38um with spectral resolutions, R∼60-600. For all sources in the LMC, we adopt a distance modulus of 18.49±0.05. See section 2 for further explanations. File Summary:
