Stark broadening models for plasma diagnostics

Journal of Physics D: Applied Physics, 2014
A review of the models used for the calculation of the Stark broadening spectrum for plasmas is presented. The aim is to provide an overview of the related theories using a simple formalism, useful for an introduction to the study of this phenomenon, which is encountered in plasma diagnostics.

Stark Broadening under Extreme Plasma Conditions

Physica Scripta, 1999
Broadening of spectral lines of atoms and ions primarily caused by electric fields from plasma electrons and ions can be important at electron densities ranging from Ne ≈ 0.1 cm-3 (interstellar molecular clouds) to Ne 1025 cm-3 (laser-fusion targets, atmospheres of neutron stars), or Ne 1027 cm-3 (stellar interiors).

Stark broadening of C IV lines

Journal of Physics B: Atomic, Molecular and Optical Physics, 1993
Analyses of C IV lines in laboratory measurements and astrophysical high resolution spectroscopy indicate that present Stark broadening data for multielectron atoms fail due to the neglect of or an insufficient description of ion broadening. A new method for the computation of complete Stark profiles is developed using the impact approximation and ...

Relaxation treatment of molecular stark broadening

Journal of Molecular Spectroscopy, 1968
The Liouville operator formalism is applied to the development of a relaxation theory treatment for the electronic Stark broadening of molecular electronic-vibrational system spectral lines. The results are applied to the broadening in the Schumann-Runge system of O 2 at temperatures 3000°K ⪕ T ⪕ 18 000°K and a relative density of one.

Stark Broadening in White Dwarf Atmospheres

1993
Recently, Bergeron, Saffer, & Liebert (1992; BSL hereafter) have obtained a new mass distribution for 129 hot (T eff > 13,000 K) DA white dwarfs by fitting observed line profiles to model atmosphere calculations. In the course of the analysis, several problems were encountered with the physics involved in the models.
