Stark Broadening of several Ne II, Ne III and O III Spectral Lines for the Stark-B Database

TL;DR

This paper calculates missing Stark broadening parameters for Ne II, Ne III, and O III spectral lines using the semiclassical perturbation method to enhance stellar atmosphere analysis.

Contribution

It provides new Stark broadening data for specific spectral lines, filling gaps in the STARK-B database for astrophysical applications.

Findings

Calculated Stark broadening parameters for 15 Ne II and 5 O III multiplets.

Determined impact broadening parameters for Ne II, Ne III, and O III lines.

Data will be integrated into the STARK-B database for astrophysics.

Abstract

In order to complete Stark broadening data for Ne II, and O III lines, needed for analysis of stellar atmospheres, we determined, within the semiclassical perturbation method, the missing Stark broadening parameters for the broadening by collisions with protons and ionized helium, for 15 Ne II and 5 O III multiplets. Also, electron, proton, and ionized helium impact broadening parameters for an important Ne II multiplet in the visible part of the spectrum, and for three Ne III multiplets, were calculated. The obtained data will be included in the STARK-B database, which is a part of Virtual Atomic and Molecular Data Center.
