In this review we focus on the fundamental theory of magnetohydrodynamic reconnection,
together with applications to understanding a wide range of dynamic processes in the solar …

Magnetic flux emergence from the solar convection zone into the overlying atmosphere is
the driver of a diverse range of phenomena associated with solar activity. In this article, we …

Abstract The Interface Region Imaging Spectrograph (IRIS) small explorer spacecraft
provides simultaneous spectra and images of the photosphere, chromosphere, transition …

Context. Numerical simulations of stellar convection and photospheres have been
developed to the point where detailed shapes of observed spectral lines can be explained …

In the lower solar atmosphere, the chromosphere is permeated by jets known as spicules, in
which plasma is propelled at speeds of 50 to 150 kilometers per second into the corona. The …

In this paper, we study the heating of the magnetized solar chromosphere induced by the
large fraction of neutral atoms present in this layer. The presence of neutrals, together with …

Context. Partially ionized plasma is usually described by a single-fluid approach, where the
ion-neutral collision effects are expressed by Cowling conductivity in the induction equation …

We derive self-consistent formalism for the description of multi-component partially ionized
solar plasma, by means of the coupled equations for the charged and neutral components …

We present a comprehensive radiative magnetohydrodynamic simulation of the quiet Sun
and large solar active regions. The 197 Mm wide simulation domain spans from 18 (10) Mm …

We present results from the first self-consistent multi-fluid simulations of chromospheric
magnetic reconnection in a weakly ionized reacting plasma. We simulate two-dimensional …
