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…
On the X-ray temperature of hot gas in diffuse nebulae
J. A. Toalá, S. J. Arthur
X-ray emitting diffuse nebulae around hot stars are observed to have soft-band temperatures in the narrow range [1-3] K, independent of the stellar wind parameters an…
Turbulence in the Ionized Gas of the Orion Nebula
S. J. Arthur, S. -N. X. Medina, W. J. Henney
In order to study the nature, origin, and impact of turbulent velocity fluctuations in the ionized gas of the Orion Nebula, we apply a variety of statistical techniques to observed…
Turbulence in simulated HII regions
S. -N. X. Medina, S. J. Arthur, W. J. Henney +2
We investigate the scale dependence of fluctuations inside a realistic model of an evolving turbulent HII region and to what extent these may be studied observationally. We find th…
