Stark broadening parameter tables for O VII and Mg XI [PDF]
By using the semiclassical-perturbation formalism, we have calculated electron-, proton-, and He III-impact line widths and shifts for 14 O VII multiplets and 18 Mg XI multiplets, of importance for research, diagnostic and modeling of various ...

REGAT: A permanent GPS network in Algeria, configuration and first results
The REGAT (“REseau Géodésique de l'ATlas”) geodetic network is composed of 53 continuously–recording GPS stations distributed in the Algerian Atlas. It spans the whole width of the Algerian coast and reaches 300 km inland, with inter-sites distance of ...

Stark broadening parameter tables for neutral zinc spectral lines [PDF]
Using a semiclassical approach, we have calculated electron−, proton− and He II−impact line widths and shifts for 32 Zn I multiplets as a function of temperature and perturber density.

Stark broadening parameter tables for In III, Tl III and Pb IV [PDF]
Using a semiclassical approach, we have calculated electron-, proton-, and ionized helium-impact line widths and shifts for 20 In III multiplets for perturber densities 1014− 1020 cm−3 and 2 Tl III multiplets for perturber densities 1017 − 1020 ...

The relation between stellar magnetic field geometry and chromospheric activity cycles - I. The highly variable field of ɛ Eridani at activity minimum [PDF]
The young and magnetically active K dwarf Epsilon Eridani exhibits a chromospheric activity cycle of about 3 years. Previous reconstructions of its large-scale magnetic field show strong variations at yearly epochs.
