Classification of Solar Radio Spectrum Based on Swin Transformer [PDF]
Universe, 2022 Solar radio observation is a method used to study the Sun. It is very important for space weather early warning and solar physics research to automatically classify solar radio spectrums in real time and judge whether there is a solar radio burst. As the

Incoherent Solar Radio Emission [PDF]
Frontiers in Astronomy and Space Sciences, 2020 Incoherent solar radio radiation comes from the free-free, gyroresonance, and gyrosynchrotron emission mechanisms. Free-free is primarily produced from Coulomb collisions between thermal electrons and ions. Gyroresonance and gyrosynchrotron result from the acceleration of low-energy electrons and mildly relativistic electrons, respectively, in the ...

Imaging spectroscopy of solar radio burst fine structures. [PDF]
Nat Commun, 2017 Solar radio observations provide a unique diagnostic of the outer solar atmosphere. However, the inhomogeneous turbulent corona strongly affects the propagation of the emitted radio waves, so decoupling the intrinsic properties of the emitting source ...

Low Altitude Solar Magnetic Reconnection, Type III Solar Radio Bursts, and X-ray Emissions. [PDF]
Sci Rep, 2018 Type III solar radio bursts are the Sun’s most intense and frequent nonthermal radio emissions. They involve two critical problems in astrophysics, plasma physics, and space physics: how collective processes produce nonthermal radiation and how magnetic ...

Exploring the Circular Polarisation of Low–Frequency Solar Radio Bursts with LOFAR [PDF]
Solar Physics, 2021 The Sun is an active star that often produces numerous bursts of electromagnetic radiation at radio wavelengths. Low frequency radio bursts have recently been brought back to light with the advancement of novel radio interferometers.

A Broadband Solar Radio Dynamic Spectrometer Working in the Millimeter-wave Band
Astrophysical Journal Supplement Series, 2022 Most solar radio telescopes operate below ∼18 GHz and cannot realize a complete frequency coverage of the microwave spectrum, especially in the optically thin regime during solar bursts, which can provide unique information about the magnetic field in ...
