The Effect of Flow and Magnetic Twist on Resonant Absorption of Slow MHD Waves in Magnetic Flux Tubes
Mohammad Sadeghi, Karam Bahari, Kayoomars Karami
Observations show that there are twisted magnetic flux tubes and plasma flow throughout the solar atmosphere. The main purpose of this work is to obtain the damping rate of sausage…
Phase Mixing of Kink MHD Waves in the Solar Corona: Viscous Dissipation and Heating
Zanyar Ebrahimi, Roberto Soler, Kayoomars Karami
Magnetohydrodynamic (MHD) kink waves have been observed frequently in solar coronal flux tubes, which makes them a great tool for seismology of the solar corona. Here, the effect o…
The effect of magnetic twist on resonant absorption of slow sausage waves in magnetic flux tubes
Mohammad Sadeghi, Kayoomars Karami
Observations show that twisted magnetic flux tubes are present throughout the sun's atmosphere. The main aim of this work is to obtain the damping rate of sausage modes in the pres…
The effect of a twisted magnetic field on the phase mixing of the kink magnetohydrodynamic waves in coronal loops
Zanyar Ebrahimi, Kayoomars Karami, Roberto Soler
There are observational evidences for the existence of twisted magnetic field in the solar corona. This inspires us to investigate the effect of a twisted magnetic field on the evo…
Resonant absorption of kink magnetohydrodynamic waves by a magnetic twist in coronal loops
Zanyar Ebrahimi, Kayoomars Karami
There is ample evidence of twisted magnetic structures in the solar corona. This motivates us to consider the magnetic twist as the cause of Alfven frequency continuum in the coron…
Torsional Alfven waves in stratified and expanding magnetic flux tubes
K. Karami, K. Bahari
The effects of both density stratification and magnetic field expansion on torsional Alfven waves in magnetic flux tubes are studied. The frequencies, the period ratio P1/P2 of the…
