We present an overview on our project to study the extended atmospheres and
dust formation zones of Mira stars using coordinated observations with the Very
Large Telescope Interferometer (VLTI), the Very Long Baseline Array (VLBA), and
the Atacama Pathfinder Experiment (APEX). The data are interpreted using an
approach of combining recent dynamic model atmospheres with a radiative
transfer model of the dust shell, and combining the resulting model structure
with a maser propagation model.Comment: 5 pages, to appear in Proc. of "Why Galaxies Care About AGB Stars
