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…

Resonant Absorption of Kink MHD Waves in Inclined and Asymmetric Coronal Loops

Sirwan Amiri, Kayoomars Karami, Zanyar Ebrahimi

This paper separately evaluates the effects of inclination and asymmetry of solar coronal loops on the resonant absorption of kink magnetohydrodynamic (MHD) oscillations. We modell…

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 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…

The effect of twisted magnetic field on the resonant absorption of MHD waves in coronal loops

K. Karami, K. Bahari

The standing quasi modes in a cylindrical incompressible flux tube with magnetic twist that undergoes a radial density structuring is considered in ideal magnetohydrodynamics (MHD)…

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…
