A novel fine spectral structure of solar radio bursts with periodic beaded stripes observed by CBSm of CMP-II by Li et al.

2025-08-19

Substantial fine structures, such as zebras, drifting bursts, spikes, and fibers have been reported during the past decades of observations of solar radio bursts. These fine structures are frequently associated with the wide-band continuum such as type-IV bursts, at both metric and decametric wavelengths. They carry important information about the radiation process and coronal conditions. Previous studies have reported the so-called narrow-band stripes (e.g., Chernov 2008), characterized by a group […]

Polarization Analysis of Type III Langmuir/Z-mode Waves with Coherent Magnetic Component Observations by Solar Orbiter by T. Formánek et al.

2025-08-05

Type III solar radio bursts are generated by beams of energetic electrons propagating through interplanetary space. These electron beams, released from the Sun, travel along the Parker spiral and grow Langmuir waves through a kinetic instability in the electron velocity distribution function. The generated Langmuir waves subsequently undergo mode conversion, producing a radio emission at the plasma frequency or its harmonic. Langmuir waves are electrostatic waves generating the electric field […]
