Magnetohydrodynamic simulations are performed for torsional Alfvén waves propagating along an open magnetic flux tube in the solar atmosphere. It is shown that, if the root mean square of the perturbation is greater than ~1 km s-1 in the photosphere, (1) the transition region is lifted up to more than ~5000 km (i.e., the spicule is produced), (2) the energy flux enough for heating the quiet corona (~3.0×105 ergs s-1 cm−2) is transported into the corona, and (3) nonthermal broadening of emission… 

NONLINEAR PROPAGATION OF ALFVÉN WAVES DRIVEN BY OBSERVED PHOTOSPHERIC MOTIONS: APPLICATION TO THE CORONAL HEATING AND SPICULE FORMATION

We have performed MHD simulations of Alfvén wave propagation along an open flux tube in the solar atmosphere. In our numerical model, Alfvén waves are generated by the photospheric granular motion.

The Heating of Solar Coronal Loops by Alfvén Wave Turbulence

In this paper we further develop a model for the heating of coronal loops by Alfvén wave turbulence (AWT). The Alfvén waves are assumed to be launched from a collection of kilogauss flux tubes in the

The solar chromosphere contains thin, highly dynamic strands of plasma known as spicules. Recently, it has been suggested that the smallest and fastest (Type II) spicules are identical to

The Heating of Coronal Loops in Solar Active Regions

The active region corona is believed to be heated by magnetic disturbances that propagate into the corona from the convection zone below. A reduced magnetohydrodynamic (MHD) model of Alfvén waves in

Spectroscopic Observations and Modelling of Impulsive Alfvén Waves Along a Polar Coronal Jet

Context. The magnetic reconnection in the solar corona results in impulsively generated Alfven waves, which drive a polar jet. Aims. Using the Hinode/EIS 2 �� spectroscopic observations, we study the

Generation and propagation of Alfvén waves in solar atmosphere

Abstract The propagation of Alfvén waves from the photosphere into the corona with regard to the fine structure of the magnetic field is considered. The energy flux of Alfvén–type waves generated in

We review our recent results of global one-dimensional (1-D) MHD simulations for the acceleration of solar and stellar winds. We impose transverse photospheric motions corresponding to the

The solar atmosphere may be heated by Alfvén waves that propagate up from the convection zone and dissipate their energy in the chromosphere and corona. To further test this theory, we consider wave
