Balmer-alpha,-beta and-gamma lines have been calculated using computer simulations
including ion dynamics effects for equilibrium and non-equilibrium conditions. The results …

Redshifted components of chromospheric emission lines in the hard X-ray impulsive phase
of solar flares have recently been studied through their 30 s evolution with the high …

The present paper is devoted to the interpretation of linear polarization data obtained in 14
quiescent prominences with the Pic-du-Midi coronagraph-polarimeter by JL Leroy, in the two …

Balmer lines in cool dwarf stars. 1. Basic influence of atmospheric models ADS Classic is now
deprecated. It will be completely retired in October 2019. This page will automatically redirect to …

The determination of photospheric abundances in late-type stars from spectroscopic
observations is a well-established field, built on solid theoretical foundations. Improving …

“Stark broadening” theory and calculations have been extensively developed for about 50
years. The theory can now be considered as mature for many applications, especially for …

The generation of high-energetic species in plasma by discharge in liquids makes it suitable
for applications such as water treatment. Effective reduction of input power and an increase …

VLT-UVES high resolution spectra of seven turnoff stars in the metal-poor globular cluster
NGC 6397 have been obtained. Atmospheric parameters and abundances of several …

We describe a new method for computing opacity distribution functions (ODFs) for model
atmosphere calculations. The method is tailored to model the atmospheres of individual …

Although the spectral lines of hydrogen contain valuable information on the physical
properties of a variety of astrophysical plasmas, including the upper solar chromosphere …
