Segregation of isotopes of heavy metals due to light-induced drift: results and problems
A. Sapar, A. Aret, R. Poolamäe +1
Atutov and Shalagin (1988) proposed light-induced drift (LID) as a physically well understandable mechanism to explain the formation of isotopic anomalies observed in CP stars. We…
Formulae for study of LID induced diffusion in CP star model atmospheres
A. Sapar, A. Aret, L. Sapar +1
Formulae suitable for computing light-induced drift (LID) acceleration and corresponding diffusional segregation of isotopes in CP star model atmospheres are given.
A Pan-Spectral Method of Abundance Determination
A. Sapar, A. Aret, L. Sapar +1
We propose a new method for determination of element abundances in stellar atmospheres aimed for the automatic processing of high-quality stellar spectra. The pan-spectral method i…
Particle diffusion in atmospheres of CP stars
A. Aret, A. Sapar
We give concisely the formulae governing diffusion of chemical elements and their isotopes in quiescent stellar atmospheres, due to electrostatic, gravitational and radiation field…
