GUI for the e – CALLISTO Data: Analysis of Type II and Type III Solar Radio Bursts by Yashan Hettiarachchi et al.

July 23, 2024

Solar radio bursts (SRBs) are sudden peaks in the low-frequency radio emissions originating from the sun. These emissions can also help predict space weather events that could have adverse effects on satellite communications and the global energy grid. A thorough understanding of this phenomenon demands the collection and analysis of solar emission data over vast geographical and time scales. In this regard, the e-CALLISTO network plays a major role through […]

Energetics of compressive waves in the solar corona by Francesco Azzollini et al

July 2, 2024

Inelastic scattering off moving or oscillating density fluctuations leads to broadening of radio signals propagating in the solar corona and solar wind. Using an anisotropic density fluctuation model from the kinetic scattering theory for solar radio bursts, we deduce the plasma velocities (perpendicular to the line of sight) required to explain observations of spacecraft signal frequency broadening. The kinetic energy associated with these inferred bulk velocities cascades to smaller and […]
