Alfvén Wave Dissipation in the Solar Chromosphere

S. D. T. Grant, D. B. Jess, T. V. Zaqarashvili +7

Magneto-hydrodynamic (MHD) Alfvén waves have been a focus of laboratory plasma physics and astrophysics for over half a century. Their unique nature makes them ideal energy transpo…

Active modes and dynamical balances in MRI-turbulence of Keplerian disks with a net vertical magnetic field

D. Gogichaishvili, G. Mamatsashvili, W. Horton +1

We studied dynamical balances in magnetorotational instability (MRI) turbulence with a net vertical field in the shearing box model of disks. Analyzing the turbulence dynamics in F…

Association between Tornadoes and Instability of Hosting Prominence

Irakli Mghebrishvili, Teimuraz V. Zaqarashvili, Vasil Kukhianidze +4

We studied the dynamics of all prominence tornadoes detected by the Solar Dynamics Observatory/Atmospheric Imaging Assembly from 2011 January 01 to December 31. In total, 361 event…

E and B polarizations from inhomogeneous and solar surface turbulence

Axel Brandenburg, Andrea Bracco, Tina Kahniashvili +4

Gradient- and curl-type or E- and B-type polarizations have been routinely analyzed to study the physics contributing to the cosmic microwave background polarization and galactic f…

Periodicity in the Light Curve of P Cygni - Indication for a Binary Companion?

Amir M. Michaelis, Amit Kashi, Nino Kochiashvili

We use observations of the Luminous Blue Variable (LBV) P Cygni spanning seven decades, along with signal processing methods, to identify a periodicity in the stellar luminosity. W…

Spectropolarimetric inversions of the Ca ii 8542 Å line in a M-class solar flare

D. Kuridze, V. Henriques, M. Mathioudakis +3

We study the M1.9 class solar flare SOL2015-09-27T10:40 UT using high-resolution full-Stokes imaging spectropolarimetry of the Ca ii 8542 Å line obtained with the CRISP imaging spe…

Evidence for precursors of the coronal hole jets in solar bright points

Salome R. Bagashvili, Bidzina M. Shergelashvili, Darejan R. Japaridze +5

A set of 23 observations of coronal jet events that occurred in coronal bright points has been analyzed. The focus was on the temporal evolution of the mean brightness before and d…

Equatorial magnetohydrodynamic shallow water waves in the solar tachocline

T. V. Zaqarashvili

The influence of a toroidal magnetic field on the dynamics of shallow water waves in the solar tachocline is studied. A sub-adiabatic temperature gradient in the upper overshoot la…
