Modeling the Subsurface Structure of Sunspots
H. Moradi, C. Baldner, A. C. Birch +19
While sunspots are easily observed at the solar surface, determining their subsurface structure is not trivial. There are two main hypotheses for the subsurface structure of sunspo…

Photospheric high-frequency acoustic power excess in sunspot umbra: signature of magneto-acoustic modes
S. Zharkov, S. Shelyag, V. Fedun +2
We present observational evidence for the presence of MHD waves in the solar photosphere deduced from SOHO/MDI Dopplergram velocity observations. The magneto-acoustic perturbations…

Acoustic wave propagation in the solar sub-photosphere with localised magnetic field concentration: effect of magnetic tension
S. Shelyag, S. Zharkov, V. Fedun +2
Aims. In this paper we analyse numerically the propagation and dispersion of acoustic waves in the solar-like sub-photosphere with localised non-uniform magnetic field concentratio…
