Photoionization modelling of circumstellar nebulae using irregular grains
P. Jiménez-Hernández, S. J. Arthur, D. Guirado +4
We study the effects of using the optical properties of irregular hexahedral grains in photoionization models of circumstellar nebulae around evolved stars. Dust opacities for the…

Formation and X-ray emission from hot bubbles in planetary nebulae - III. The impact of [Wolf-Rayet]-type winds
Rogelio Orozco-Duarte, Jesús A. Toalá, S. Jane Arthur +3
We use radiation-hydrodynamical simulations to investigate the formation and synthetic X-ray emission of hot bubbles within planetary nebulae (PNe) driven by the powerful winds of…
