Hβ Stark broadening in cold plasmas with low electron densities calibrated with Thomson scattering [PDF]
, 2012 In the present work Stark broadening measurements have been carried out on low electron density (neb5·1019 m-3) and (relatively) low gas temperature (Tgb1100 K) argon–hydrogen plasma, under low-intermediate pressure conditions (3 mbar–40 mbar).

Stark Widths of Ar II Spectral Lines in the Atmospheres of Subdwarf B Stars
Atoms, 2017 Stark broadening parameters are of interest for many problems in astrophysics and laboratory plasmas investigation. Ar II spectral lines are observed in many kinds of stellar atmospheres such as the atmospheres of B-Type stars and subdwarf B stars.

Stark broadening of N II spectral lines [PDF]
Serbian Astronomical JournalThe Stark broadening parameters, widths, and shifts, for spectral lines within the 45 N II multiplets, were calculated for collisions with electrons, protons and helium ions, by using the semiclassical perturbation method. The obtained data were

On the Stark broadening of Ru III spectral lines [PDF]
Bulletin of Natural Sciences Research, 2021 Stark broadening parameters, full widths at half maximum (FWHM) and shifts for spectral lines within six multiplets of doubly charged ruthenium ions have been calculated, for an electron density of 10 17 cm-3 and temperature range from 10 000 K to 160 ...

Stark Broadening of Co II Lines in Stellar Atmospheres
Data, 2020 Data for Stark full widths at half maximum for 46 Co II multiplets were calculated using a modified semiempirical method. In order to show the applicability and usefulness of this set of data for research into white dwarf and A type star atmospheres, the

Influence of improved Stark broadening data on chromium spectral lines
, 2018 Stellar atmosphere modeling and chemical abundance determinations require the knowledge of spectral line shapes. A spectral line is not infinitely sharp but has a finite width and shape, due to various line broadening mechanisms. This phenomenon is known
