Coronal quasi-periodic fast-mode propagating wave trains
Y Shen, X Zhou, Y Duan, Z Tang, C Zhou, S Tan - Solar Physics, 2022 - Springer
Quasi-periodic, fast-mode propagating (QFP) wave trains in the corona have been studied
intensively over the last decade, thanks to the full-disk, high spatio-temporal resolution, and …

Strength of the solar coronal magnetic field–a comparison of independent estimates using contemporaneous radio and white-light observations
We estimated the coronal magnetic field strength (BB) during the 23 July 2016 coronal mass
ejection (CME) event using i) the flux rope structure of the CME in the white-light …

A coronal seismological study with streamer waves
We present a novel method to evaluate the Alfvén speed and the magnetic field strength
along the streamer plasma sheet in the outer corona. The method is based on recent …

Solar type IIIb radio bursts as tracers for electron density fluctuations in the corona
V Mugundhan, K Hariharan, R Ramesh - Solar Physics, 2017 - Springer
We present an estimation of the electron density modulation index (δ N e N e δN_eN_e) for
the first time using solar type IIIb radio burst observations. The mean value of δ N e N e …

LOFAR observations of the quiet solar corona
Context. The quiet solar corona emits meter-wave thermal bremsstrahlung. Coronal radio
emission can only propagate above that radius, R ω, where the local plasma frequency …
