Formation of small-scale magnetic elements: surface mechanism
A. S. Gadun, V. A. Sheminova, S. K. Solanki
We present the first results of a two-dimensional MHD simulation of the solar magnetogranulation. The medium was assumed to be compressible, gravitationally stratified, radiatively…
Evolution of solar magnetic tubes and its manifestation in Stokes parameters
V. A. Sheminova, A. S. Gadun
Basic scenarios and mechanisms for the formation and decay of small-scale magnetic elements and their manifestation in synthesized Stokes profiles of the Fe I 15648.5 A infrared li…
Absolute shifts of Fe I and Fe II lines in solar active regions (disk center)
P. N. Brandt, A. S. Gadun, V. A. Sheminova
We estimated absolute shifts of Fe I and Fe II lines from Fourier-transform spectra observed in solar active regions. Weak Fe I lines and all Fe II lines tend to be red-shifted as…
Convective shifts of iron lines in the spectrum of the solar photosphere
V. A. Sheminova, A. S. Gadun
The influence of the convective structure of the solar photosphere on the shifts of spectral lines of iron was studied. Line profiles in the visible and infrared spectrum were synt…
Fourier analysis of Fe I lines in the spectra of the Sun, α Centauri A, Procyon, Arcturus, and Canopus
V. A. Sheminova, A. S. Gadun
We used spectral observations of Fe I line profiles with a 200 000 resolution to determine micro and macroturbulent velocities in the atmospheres of the Sun as a star, α Cen A, Pro…
