Long characteristics vs. short characteristics in 3D radiative transfer simulations of polarized radiation

A. de Vicente, T. del Pino Alemán, J. Trujillo Bueno

We compare maps of scattering polarization signals obtained from three-dimensional (3D) radiation transfer calculations in a magneto-convection model of the solar atmosphere using…

Two-fluid simulations of Rayleigh-Taylor instability in a magnetized solar prominence thread. I. Effects of prominence magnetization and mass loading

B. Popescu Braileanu, V. S. Lukin, E. Khomenko +1

Solar prominences are formed by partially ionized plasma with inter-particle collision frequencies generally warranting magnetohydrodynamic treatment. In this work, we explore the…

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

B. Popescu Braileanu, V. S. Lukin, E. Khomenko +1

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…

Two-fluid simulations of waves in the solar chromosphere I: numerical code verification

B. Popescu Braileanu, V. S. Lukin, E. Khomenko +1

Solar chromosphere consists of a partially ionized plasma, which makes modeling the solar chromosphere a particularly challenging numerical task. Here we numerically model chromosp…

Three-dimensional simulations of solar magneto-convection including effects of partial ionization

E. Khomenko, N. Vitas, M. Collados +1

Over the last decades, realistic 3D radiative-MHD simulations have become the dominant theoretical tool for understanding the complex interactions between the plasma and the magnet…

MHDSTS: a new explicit numerical scheme for simulations of partially ionised solar plasma

P. A. González-Morales, E. Khomenko, T. P. Downes +1

The interaction of plasma with magnetic field in the partially ionised solar atmosphere is frequently modelled via a single-fluid approximation, which is valid for the case of a st…

Numerical simulations of quiet Sun magnetic fields seeded by Biermann battery

E. Khomenko, N. Vitas, M. Collados +1

The magnetic fields of the quiet Sun cover at any time more than 90\% of its surface and their magnetic energy budget is crucial to explain the thermal structure of the solar atmos…

High frequency waves in the corona due to null points

I. C. Santamaria, E. Khomenko, M. Collados +1

This work aims to understand the behavior of non-linear waves in the vicinity of a coronal null point. In previous works we have showed that high frequency waves are generated in s…

Simulated interaction of MHD shock waves with a complex network-like region

Irantzu C. Santamaria, Elena Khomenko, Manuel Collados +1

We provide estimates of the wave energy reaching the solar chromosphere and corona in a network-like magnetic field topology, including a coronal null point. The waves are excited…

Heating of the partially ionized solar chromosphere by waves in magnetic structures

S. Shelyag, E. Khomenko, A. de Vicente +1

In this paper, we show a "proof of concept" of the heating mechanism of the solar chromosphere due to wave dissipation caused by the effects of partial ionization. Numerical modeli…

On the robustness of the pendulum model for large-amplitude longitudinal oscillations in prominences

M. Luna, J. Terradas, E. Khomenko +2

Large-amplitude longitudinal oscillations (LALOs) in prominences are spectacular manifestations of the solar activity. In such events nearby energetic disturbances induce periodic…

Rayleigh-Taylor instability in prominences from numerical simulations including partial ionization effects

E. Khomenko, A. Diaz, A. de Vicente +2

We study the Rayleigh-Taylor instability (RTI) at a prominence-corona transition region in a non-linear regime. Our aim is to understand how the presence of neutral atoms in the pr…

Characterization of horizontal flows around solar pores from high-resolution time series of images

S. Vargas Dominguez, A. de Vicente, J. A. Bonet +1

Though there is increasing evidence linking the moat flow and the Evershed flow along the penumbral filaments, there is not a clear consensus regarding the existence of a moat flow…

Big Science with a Small Budget: Non-Embarrassingly Parallel Applications in a Non-Dedicated Network of Workstations

Angel de Vicente, Nayra Rodriguez

Many astronomers and astrophysicists require large computing resources for their research, which are usually obtained via dedicated (and expensive) parallel machines. Depending on…
