Simulation of Thermal Nonequilibrium Cycles in the Solar Wind
The Astrophysical JournalThermal nonequilibrium (TNE) is a condition of the plasma in the solar corona in which the local rate of energy loss due to radiation increases to the point that it cannot be sustained by the various heating terms acting on the plasma, precluding the ...

Solar Transient Events and their Importance for Coronal Heating
Science Progress, 2004 Over the last decade, the uninterrupted high resolution coverage of the Sun both from the excellent range of telescopes aboard many spacecrafts and from ground-based instruments has led to a wealth of observations of small-scale dynamic events observed from the chromosphere to the transition region and corona.

Space Weather, Volume 24, Issue 4, April 2026.Abstract Storm‐time equatorial plasma bubble (EPB) dynamics play a critical role in space weather impacts on communication and navigation systems, yet the mechanisms governing their formation and evolution under storm conditions remain poorly understood.

Journal of Geophysical Research: Space Physics, Volume 131, Issue 4, April 2026.Abstract The state of Mars' induced magnetosphere is highly dependent on upstream solar wind conditions. Changes in dynamic pressure alter the locations of magnetospheric boundaries such as the bow shock and induced magnetosphere boundary, while the orientation of the interplanetary magnetic field (IMF) impacts the formation of the bow shock.

On the theory of coronal heating mechanisms [PDF]
Theoretical models describing solar coronal heating mechanisms are reviewed in some detail. The requirements of chromospheric and coronal heating are discussed in the context of the fundamental constraints encountered in modelling the outer solar ...

New Evidence that Magnetoconvection Drives Solar–Stellar Coronal Heating
The Astrophysical Journal Letters, 2017 Abstract How magnetic energy is injected and released in the solar corona, keeping it heated to several million degrees, remains elusive. Coronal heating generally increases with increasing magnetic field strength. From a comparison of a nonlinear force-free model of the three-dimensional active region coronal field to observed extreme ...

Modeling the Propagation of Slow Magnetoacoustic Waves in a Multistranded Coronal Loop
The Astrophysical JournalWe study the propagation properties of slow magnetoacoustic waves in a multithermal coronal loop using a 3D MHD model, for the first time. A bundle of 33 vertical cylinders, each of 100 km radius, randomly distributed over a circular region of radius 1 ...

Coronal Heating versus Solar Wind Acceleration
, 2004 Parker's initial insights from 1958 provided a key causal link between the heating of the solar corona and the acceleration of the solar wind. However, we still do not know what fraction of the solar wind's mass, momentum, and energy flux is driven by Parker-type gas pressure gradients, and what fraction is driven by, e.g., wave-particle interactions ...

Turbulent resistive heating of solar coronal arches
The Astrophysical Journal, 1983 The possibility that coronal heating occurs by means of anomalous Joule heating by electrostatic ion cyclotron waves is examined, with consideration given to currents running from foot of a loop to the other. It is assumed that self-fields generated by the currents are absent and currents follow the direction of the magnetic field, allowing the plasma ...

Global Change Biology, Volume 32, Issue 4, April 2026.We present ‘HomoTherm’, a human heat budget model for simulating humans and related species with diverse traits in diverse environments. It is part of the NicheMapR package for biophysical modelling and is a multi‐part extension of the ‘endoR’ function.
