Dopita, MichaelSutherland, Ralph2015-12-132015-12-130004-637Xhttp://hdl.handle.net/1885/90230We present theoretical self-consistent models of planetary nebulae including detailed dust heating. Galactic, LMC, and SMC abundance patterns are used in a comparison of dusty and dust-free models. We show that dust has a strong effect on the thermal structure and emission-line spectrum of highly ionized species in planetary nebulae. These models have implications for excitation and energy balance methods for determining central star temperatures. We present results for [O III] λ5007 and [N II] λ6583 lines for Galactic, LMC, and SMC abundances.Keywords: Dust, extinction; ISM: abundances; Planetary nebulae: general radiative transfer20002015-12-12
