Atmospheric Electrification in the Solar System [PDF]
Surveys in Geophysics, 2006 Atmospheric electrification is not a purely terrestrial phenomenon: all Solar System planetary atmospheres become slightly electrified by cosmic ray ionisation. There is evidence for lightning on Jupiter, Saturn, Uranus and Neptune, and it appears likely to exist on Mars, Venus and Titan.

Frontiers in Astronomy and Space Sciences, 2022 Solar flares are transient yet dramatic events in the atmosphere of the Sun, during which a vast amount of magnetic energy is liberated. This energy is subsequently transported through the solar atmosphere or into the heliosphere, and together with ...

Magnetohydrostatic modeling of the solar atmosphere
Science China Technological Sciences, 2022 Understanding structures and evolutions of the magnetic fields and plasma in multiple layers on the Sun is very important. A force-free magnetic field which is an accurate approximation of the solar corona due to the low plasma $β$ has been widely studied and used to model the coronal magnetic structure.

Frontiers in Astronomy and Space Sciences, 2019 Diagnosing the solar atmospheric plasma is one of the major challenges in solar physics. Magnetohydrodynamic (MHD) waves, by means of applying the powerful concept of solar magneto-seismology (SMS), provide a tool to obtain diagnostic insight into the ...

Frontiers in Astronomy and Space Sciences, 2023 During solar flares a tremendous amount of magnetic energy is released and transported through the Sun’s atmosphere and out into the heliosphere. Despite over a century of study, many unresolved questions surrounding solar flares are still present. Among

Flows in the solar atmosphere due to the eruptions on the 15th July, 2002 [PDF]
, 2005 <p>Which kind of flows are present during flares? Are they compatible with the present understanding of energy release and which model best describes the observations? We analyze successive flare events in order to answer these questions.

Frontiers in Astronomy and Space Sciences, 2019 Propagating kink waves have been observed in many magnetic waveguides in the solar atmosphere, like coronal magnetic loops, spicules, and fine structures of prominences. There are also observational evidences that these waves are damped.

The magnetic field in the solar atmosphere [PDF]
The Astronomy and Astrophysics Review, 2014 This publication provides an overview of magnetic fields in the solar atmosphere with the focus lying on the corona. The solar magnetic field couples the solar interior with the visible surface of the Sun and with its atmosphere. It is also responsible for all solar activity in its numerous manifestations.

Analytical Solution of the Hanle Effect in View of CLASP and Future Polarimetric Solar Studies
Atoms, 2019 We have solved a problem of the Hanle effect for the hydrogen Lyman- α line in an intuitive and straightforward way. The Stokes parameters amid an anisotropic radiation field and a magnetic field are derived as an analytical formula which ...
