Heating mechanisms of the solar corona. [PDF]
Proc Jpn Acad Ser B Phys Biol Sci, 2017 The solar corona is a tenuous outer atmosphere of the Sun. Its million-degree temperature was discovered spectroscopically in the 1940s, but its origin has been debated since then without complete convergence. Currently there are two classes of models; the wave theory and the microflare/nanoflare theory.

Kinetic Physics of the Solar Corona and Solar Wind
Living Reviews in Solar Physics, 2006 Kinetic plasma physics of the solar corona and solar wind are reviewed with emphasis on the theoretical understanding of the in situ measurements of solar wind particles and waves, as well as on the remote-sensing observations of the solar corona made by

Chromospheric Jets and Their Properties [PDF]
Iranian Journal of Astronomy and Astrophysics, 2022 In this study we review solar chromospheric jets and characteristics of them. The chromosphere and transition region are the interface between the solar photosphere and the corona, which plays a key role in the formation and acceleration of the solar ...

Astronomy & Astrophysics, 2023 Context. Vortex flows have been found in the photosphere, chromosphere, and low corona in observations and simulations. It has been suggested that vortices play an important role in channeling energy and plasma into the corona. However, the impact of vortex flows on the corona has not been studied directly in a realistic setup. Aims. We investigate the

Polarization of white-light solar corona and sky polarization effect during total solar eclipse on March 29, 2006 [PDF]
Serbian Astronomical Journal, 2019 Ground-based total solar eclipse observations are still the key method for coronal investigations. The question about its white-light degree of polarization remains unanswered.

Energy Budget in the Solar Corona
The Astrophysical Journal, 2023 This paper addresses the first direct investigation of the energy budget in the solar corona. Exploiting joint observations of the same coronal plasma by Parker Solar Probe and the Metis coronagraph aboard Solar Orbiter and the conserved equations for ...

THE ROLE OF RADIO WAVE PROPAGATION EFFECTS IN THE SOLAR CORONA TO INTERPRET THE BEHIND-LIMB BURSTS
Radio Physics and Radio Astronomy, 2016 Purpose: The radio emission propagation of solar radio bursts in the solar corona which sources are located on the far side of the Sun relative to the observer on Earth is studied.
