Plasma instability at the front of ejected electrons and Type III emission by V. Krasnoselskikh et al.

February 17, 2026

Type III bursts are usually described as a two-step process: energetic electrons excite Langmuir waves, which are then converted into radio emission near the plasma frequency (Ginzburg & Zhelezniakov 1958). The recent discovery of Fundamental-Harmonic pairs by Parker Solar Probe (PSP) shows that many fundamental type III bursts are weak and composed of short, rapidly varying elements whose intensity rises quickly and then decays more slowly at a fixed frequency […]

Solar Radio Wide‐Band Spectroscopy and Imaging Facilities of the Chinese Meridian Project Phase II by Yihua Yan et al.

February 3, 2026

Radioheliographs and wideband solar radio spectrographs are essential components of the Chinese Meridian Project (CMP)‐II (C. Wang et al., 2024) that aims to monitor the whole solar‐terrestrial chain of space weather events, from the lower solar atmosphere to near‐Earth space. This work introduce the CMP‐II radio instruments, including the MUSER‐L/I/H, the super‐wideband spectrographs of Mingantu and Chashan stations covering the wideband range of 30 MHz–15 GHz. The overall design, some […]
