Magneto-acoustic wave propagation in a magnetic flux sheet (moderate field)

Co-Authors: S. S. Hasan, O. Steiner
Temperature perturbations in a magnetic flux sheet (moderate field strength) due to waves excited by a horizontal motion at the bottom boundary. The waves higher up are predominantly acoustic (slow magneto-acoustic) that propagat ...

Magneto-acoustic wave propagation in a magnetic flux sheet (strong field)

Co-Authors: S. S. Hasan, O. Steiner
Temperature perturbations in a magnetic flux sheet (strong field) due to waves excited by a horizontal motion at the bottom boundary. The excitation generates fast magneto-acoustic wave (predominantly magnetic) along with slow mag ...

Magneto-acoustic waves in magnetic flux tube

Co-Authors: Fedun, V.; Hasan, S. S.; Erdélyi, R.
Temperature perturbations associated with the propagation of magneto-acoustic waves in a magnetic flux tube. Two scenarios of wave excitation, viz. granular buffeting and swirly motion are studied. Buffeting by granule are likely ...

Polarized radiation shows signature of magneto-acoustic wave propagation (moderate field)

Co-Authors: O. Steiner, S. S. Hasan
Variation of Stokes-V profiles of Fe I (5250.2 Å and 6302.5 Å) emerging from a small region on either side of the magnetic flux sheet (moderate field strength) as a result of wave propagation within the line-of-sight. The emerge ...

Polarized radiation shows signature of fast magneto-acoustic wave refraction (strong field)

Co-Authors: O. Steiner, S. S. Hasan
Variation of Stokes-V profiles of Fe I (5250.2 Å and 6302.5 Å) emerging from a small region on either side of the magnetic flux sheet (strong field strength). The effects of refraction of the fast (predominantly magnetic) wave ...
