Kelvin-Helmholtz instability on coronal mass ejecta in the lower corona
I. Zhelyazkov, T. V. Zaqarashvili, R. Chandra
We model an imaged Kelvin-Helmholtz (KH) instability on a coronal mass ejecta (CME) in the lower corona by investigating conditions under which kink () and magnetoh…
Overdamped Alfven waves due to ion-neutral collisions in the solar chromosphere
R. Soler, J. L. Ballester, T. V. Zaqarashvili
Alfvenic waves are ubiquitous in the solar atmosphere and their dissipation may play an important role in atmospheric heating. In the partially ionized solar chromosphere, collisio…
On the adiabatic walking of plasma waves in a pulsar magnetosphere
George I. Melikidze, Dipanjan Mitra, Janusz Gil
The pulsar radio emission is generated in the near magnetosphere of the neutron star and it has to propagate through the rest of it to emerge into the interstellar medium. An impor…
Overstability of acoustic waves in strongly magnetized anisotropic MHD shear flows
E. S. Uchava, B. M. Shergelashvili, A. G. Tevzadze +1
We present a linear stability analysis of the perturbation modes in anisotropic MHD flows with velocity shear and strong magnetic field. Collisionless or weakly collisional plasma…
Fast magnetohydrodynamic oscillation of longitudinally inhomogeneous prominence threads: an analogue with quantum harmonic oscillator
S. N. Lomineishvili, T. V. Zaqarashvili, I. Zhelyazkov +1
Previous works indicate that the frequency ratio of second and first harmonics of kink oscillations has tendency towards 3 in the case of prominence threads. We aim to study the ma…
Twisted magnetic flux tubes in the solar wind
Teimuraz Zaqarashvili, Zoltán Vörös, Yasuhito Narita +1
Magnetic flux tubes in the solar wind can be twisted as they are transported from the solar surface, where the tubes are twisted owing to photospheric motions. It is suggested that…
