Magnetoacoustic Heating of the Solar Chromosphere
Long-period acoustic waves generated in the solar convection zone can propagate radially outward through the overlying atmosphere and get resonantly absorbed in the magnetic arches of the low-lying chromospheric canopy. The resulting Poynting and acoustic flux that enters the magnetic canopy in the network regions is demonstrated to be adequate to ...

Coronal mass ejections and exoplanets: A numerical perspective
Abstract Coronal mass ejections (CMEs) are more energetic than any other class of solar phenomena. They arise from the rapid release of up to erg of magnetic energy mainly in the form of particle acceleration and bulk plasma motion. Their stellar counterparts, presumably involving much larger energies, are expected to play a fundamental role in shaping

MHD turbulence and heating of the open field-line solar corona [PDF]
This paper discusses the possibility that heating of the solar corona in open field-line regions emanating from coronal holes is due to a nonlinear cascade, driven by low-frequency or quasi-static magnetohydrodynamic fluctuations.

Propagation and damping of MHD waves in the solar atmosphere [PDF]
Quasi-periodic disturbances have been observed in the outer solar atmosphere for many years. Although first interpreted as upflows (Schrijver et al.

Solar EUV‐Enhancement and Thermospheric Disturbances
Abstract The increase of energetic electromagnetic flux during solar flares and particle precipitation during geomagnetic activity are among the most important sources of neutral density disturbances to the Earth's thermosphere. However, disentangling the role of X and EUV radiation during solar flares is difficult due to the rarity of sufficiently ...

The effect of colour on the thermal performance of building integrated solar collectors [PDF]
The use of solar collectors with coloured absorbers for water heating is an area of particular interest when considering their integration with buildings.

An Improved Solar Spectral Irradiance Composite Record
Abstract The solar spectral irradiance (SSI) data set is a key record for studying and understanding the energetics and radiation balance in Earth’s environment. Understanding the long‐term variations of the SSI over time scales of the 11‐years solar activity cycle and longer is critical for many Sun‐climate research topics.

Phase Mixing of Propagating Alfvén Waves in a Single-fluid Partially Ionized Solar Plasma
The phase mixing of Alfvén waves is one of the most promising mechanisms for the heating of the solar atmosphere. The damping of waves in this case requires small transversal scales, relative to the magnetic field direction; this requirement is achieved ...

Termination of Solar Cycles and Correlated Tropospheric Variability
Abstract The Sun provides the energy required to sustain life on Earth and drive our planet's atmospheric circulation. However, establishing a solid physical connection between solar and tropospheric variability has posed a considerable challenge. The canon of solar variability is derived from the 400 years of observations that demonstrates the waxing ...
