Magnetic field amplification and structure formation by the Rayleigh-Taylor instability

Autor: Braileanu, B. Popescu, Lukin, V. S., Khomenko, E.

Publikováno v: A&A 670, A31 (2023)

We report on results of high resolution two fluid non-linear simulations of the Rayleigh Taylor Instability (RTI) at the interface between a solar prominence and the corona. These follow results reported earlier by Popescu Braileanu et al. (2021a,b)

Two-fluid simulations of Rayleigh-Taylor instability in a magnetized solar prominence thread II. Effects of collisionality

Autor: Braileanu, B. Popescu, Lukin, V. S., Khomenko, E., de Vicente, A.

Publikováno v: A&A 650, A181 (2021)

In this work, we explore the dynamical impacts and observable signatures of two-fluid effects in the parameter regimes when ion-neutral collisions do not fully couple the neutral and charged fluids. The purpose of this study is to deepen our understa

Two-fluid simulations of waves in the solar chromosphere II. Propagation and damping of fast magneto-acoustic waves and shocks

Autor: Braileanu, B. Popescu, Lukin, V. S., Khomenko, E., de Vicente, A.

Publikováno v: A&A 630, A79 (2019)

Waves and shocks traveling through the solar chromospheric plasma are influenced by its partial ionization and weak collisional coupling, and may become susceptible to multi-fluid effects, similar to interstellar shock waves. In this study, we consid

3D modelling of accretion disc in eclipsing binary system V1239 Her

Autor: Lukin, V. V., Malanchev, K. L., Shakura, N. I., Postnov, K. A., Chechetkin, V. M., Utrobin, V. P.

Publikováno v: MNRAS, 2017, v. 467, pp. 2934-2942

We present the results of 3D-hydrodynamical simulations of accretion flow in the eclipsing dwarf nova V1239 Her in quiescence. The model includes the optical star filling its Roche lobe, a gas stream emanating from the inner Lagrangian point of the b

New results from MAST are presented that focus on validating models in order to extrapolate to future devices. Measurements during start-up experiments have shown how the bulk ion temperature rise scales with the square of the reconnecting field. Dur
