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

Under-Developed and Under-Utilized Eclipsing Binary Model Capabilities [PDF]
Journal of Astronomy and Space Sciences, 2012 Existing but largely unused binary star model capabilities are examined. An easily implemented scheme is parameterization of starspot growth and decay that can stimulate work on outer convection zones and their dynamos.

NLTE Analysis of High-Resolution H-Band Spectra, V: Neutral Sodium
Universe, 2023 In order to derive sodium abundances and investigate the effects of non-local thermodynamic equilibrium (NLTE) on the formation of H-band Na I lines, we update the sodium atomic model by incorporating collision rates with hydrogen from new quantum ...

Stark Widths of Yb III and Lu IV Spectral Lines
Atoms, 2019 Rare Earth Elements are important for stellar atmosphere analysis but the corresponding Stark broadening data are scarce. For Yb III and Lu IV theoretical as well as experimental data on Stark broadening parameters of spectral lines are absent in the ...

Line profiles in expanding atmospheres [PDF]
Symposium - International Astronomical Union, 1994 The analysis of the UV resonance transitions of superionized species observed in early-type stars suggests the presence of a high temperature region and an outward flow of matter (Snow & Marlborough 1976).

Stark Broadening and White Dwarfs
Open 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 ...

Electron energy-loss spectroscopy of autoionizing states of zinc [PDF]
Serbian Astronomical Journal, 2004 Autoionizing energy-loss spectra of Zn from 10.8 to 12.5 eV, for incident electron energies between 20 and 100 eV, have been recorded at scattering angles from 0° to 10°.

Stark Broadening of Several Ne II, Ne III and O III Spectral Lines for the Stark-B Database
Open 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 Widths of Na IV Spectral Lines
Atoms, 2017 Sodium is a very important element for the research and analysis of astrophysical, laboratory, and technological plasmas, but neither theoretical nor experimental data on Stark broadening of Na IV spectral lines are present in the literature.

Unifying the low-temperature photoluminescence spectra of carbon nanotubes: the role of acoustic phonon confinement [PDF]
, 2014 At low temperature the photoluminescence of single-wall carbon nanotubes show a large variety of spectral profiles ranging from ultra narrow lines in suspended nanotubes to broad and asymmetrical line-shapes that puzzle the current interpretation in ...
