Opacity for realistic 3D MHD simulations of cool stellar atmospheres
A. Perdomo García, N. Vitas, E. Khomenko +4
Context. Realistic 3D time-dependent simulations of stellar near-surface convection employ the opacity binning method for efficient and accurate computation of the radiative energy…
A study of the capabilities for inferring atmospheric information from high-spatial-resolution simulations
C. Quintero Noda, E. Khomenko, M. Collados +8
In this work, we study the accuracy that can be achieved when inferring the atmospheric information from realistic numerical magneto-hydrodynamic simulations that reproduce the spa…
Numerical simulations of prominence oscillations triggered by external perturbations
Valeriia Liakh, Manuel Luna, Elena Khomenko
Several energetic disturbances have been identified as triggers of the large-amplitude oscillations (LAOs) in prominences. However, the mechanisms for LAOs excitation are not well…
Large ion-neutral drift velocities and plasma heating in partially ionized coronal rain blobs
David Martínez-Gómez, Ramón Oliver, Elena Khomenko +1
In this paper we present a numerical study of the dynamics of partially ionized coronal rain blobs. We use a two-fluid model to perform a high-resolution 2D simulation that takes i…
Ambipolar Diffusion in the Lower Solar Atmosphere: MHD Simulations of a Sunspot
Conor D. MacBride, David B. Jess, Elena Khomenko +1
Magnetohydrodynamic (MHD) simulations of the solar atmosphere are often performed under the assumption that the plasma is fully ionized. However, in the lower solar atmosphere a re…
Observational and numerical characterization of a recurrent arc-shaped front propagating along a coronal fan
M. V. Sieyra, S. Krishna Prasad, G. Stenborg +5
Recurrent, arc-shaped intensity disturbances were detected by EUV channels in an active region. The fronts were observed to propagate along a coronal loop bundle rooted in a small…
