Stark Broadening and White Dwarfs [PDF]

open access: yesOpen Astronomy, 2011
White dwarf and pre-white dwarfs are the best types of stars for the application of Stark broadening research results in astrophysics, since in the atmospheres of these stars physical conditions are very favorable for this line broadening mechanism - in ...

Stark broadening of B IV spectral lines [PDF]

open access: yesMonthly Notices of the Royal Astronomical Society, 2016
Stark broadening parameters for 157 multiplets of helium like boron (B IV) have been calculated using the impact semiclassical perturbation formalism. Obtained results have been used to investigate the regularities within spectral series.

Stark Broadening of Several Ne II, Ne III and O III Spectral Lines for the Stark-B Database [PDF]

open access: yesOpen Astronomy, 2011
In order to complete Stark broadening data for Ne II and O III lines, needed for analysis of stellar atmospheres, we determined the missing parameters for the broadening by collisions with protons and ionized helium for 15 Ne II and 5 O III multiplets ...

Stark Broadening of In III Lines in Astrophysical and Laboratory Plasma

open access: yesOpen Astronomy, 2011
In the deeper layers of hot stellar photospheres the Stark widths of spectral lines can be comparable and even larger than the thermal Doppler widths.

Stark Broadening of Neutral Boron Lines [PDF]

open access: yesAtoms, 2019
Stark broadening parameters, width and shift, of lines within B I 2s22p−2s2ns spectral series have been calculated. Semi-classical theory in impact approximation has been applied. Temperature dependence of Stark parameters has been studied.

Stark broadening parameter tables for Ar VIII [PDF]

open access: yesSerbian Astronomical Journal, 1999
Using a semiclassical approach, we have calculated electron−, proton−, and He III−impact line widths and shifts for 9 Ar VIII transitions as a function of temperature and perturber density.

Stark Broadening of N VI Spectral Lines

open access: yesUniverse, 2023
Stark broadening parameters, line widths and shifts, for 15 N VI multiplets are calculated using semiclassical perturbation theory for temperatures from 50,000 K to 2,000,000 K, and perturber density of 1016 cm−3. As perturbers have been taken electrons,

Stark Broadening of Several Ar I Spectral Lines in the Visible Spectrum

open access: yesOpen Astronomy, 2011
In order to complete data on Stark broadening parameters for Ar I line in the visible spectrum, we determined Stark widths and shifts due to electron, proton and ionized helium impacts for nine lines (4191.0, 4259.4, 5912.1, 6043.2, 6045.0, 6752.9, 7503 ...

Stark-Broadening of Ar K-Shell Lines: A Comparison between Molecular Dynamics Simulations and MERL Results

open access: yesAtoms, 2021
Analysis of Stark-broadened spectral line profiles is a powerful, non-intrusive diagnostic technique to extract the electron density of high-energy-density plasmas. The increasing number of applications and availability of spectroscopic measurements have

Hydrogen Stark Broadened Brackett lines [PDF]

open access: yesInternational Journal of Spectroscopy, 2010
Stark-broadened lines of the hydrogen Brackett series are computed for the conditions of stellar atmospheres and circumstellar envelopes. The computation is performed within the Model Microfield Method, which includes the ion dynamic effects and makes the bridge between the impact limit at low density and the static limit at high density and in the ...
