Excitation mechanisms of C II optical permitted lines in ionized nebulae
E. Reyes-Rodríguez, J. E. Méndez-Delgado, J. García-Rojas +4
Context. Carbon is the fourth most abundant element in the universe and its distribution is critical to understanding stellar evolution and nucleosynthesis. In optical studies of i…
Relation between source and temperature fluctuations in photoionized nebulae
Luc Binette, Pierre Ferruit, Wolfgang Steffen +1
The magnitude of the temperature fluctuations (t^2) required to explain the observed inconsistencies between metallicities inferred from recombination lines and from forbidden line…
Density gradients and internal dust in the Orion nebula
L. Binette, D. Gonzalez-Gomez, Y. D. Mayya
The ionization structure of the Orion nebula can be described as a skin-like ionization structure on the surface of a dense cloud. We propose that a steep density stratification, i…
The spectral index of the ionizing continuum of quasars
L. Binette, M. Rodriguez-Martinez, I. Ballinas
The ionizing spectral energy distribution of quasars exhibits a steepening of the distribution short-ward of 1200 A. The change of the power-law index from approximately -1 to -2 s…
