Magneto-acoustic waves in sunspots from observations and numerical simulations
T. Felipe, E. Khomenko, M. Collados +1
We study the propagation of waves from the photosphere to the chromosphere of sunspots. From time series of cospatial Ca II H (including its line blends) intensity spectra and pola…
Multi-layer study of wave propagation in sunspots
T. Felipe, E. Khomenko, M. Collados +1
We analyze the propagation of waves in sunspots from the photosphere to the chromosphere using time series of co-spatial Ca II H intensity spectra (including its line blends) and p…
Where the granular flows bend
E. Khomenko, V. Martinez Pillet, S. K. Solanki +7
Based on IMaX/Sunrise data, we report on a previously undetected phenomenon in solar granulation. We show that in a very narrow region separating granules and intergranular lanes t…
Solar abundance corrections derived through 3D magnetoconvection simulations
D. Fabbian, E. Khomenko, F. Moreno-Insertis +1
We explore the effect of the magnetic field when using realistic three-dimensional convection experiments to determine solar element abundances. By carrying out magnetoconvection s…
Towards pulsation mode identification in 3-D: theoretical simulations of line profile variations in roAp stars
O. Kochukhov, E. Khomenko
Time-resolved spectroscopic observations of rapidly oscillating Ap (roAp) stars show a complex picture of propagating magneto-acoustic pulsation waves, with amplitude and phase str…
