Fine structures of radio bursts from flare star AD Leo with FAST observations
Jiale Zhang, Hui Tian, Philippe Zarka +8
Radio bursts from nearby active M-dwarfs have been frequently reported and extensively studied in solar or planetary paradigms. Whereas, their sub-structures or fine structures rem…
Polarised radio pulsations from a new T dwarf binary
H. K. Vedantham, Trent J. Dupuy, E. L. Evans +6
Brown dwarfs display Jupiter-like auroral phenomena such as magnetospheric H emission and coherent radio emission. Coherent radio emission is a probe of magnetospheric accelerat…
MOVES V. Modelling star-planet magnetic interactions of HD 189733
A. Strugarek, R. Fares, V. Bourrier +10
Magnetic interactions between stars and close-in planets may lead to a detectable signal on the stellar disk. HD 189733 is one of the key exosystems thought to harbor magnetic inte…
Spectral Analysis of Solar Radio Type III Bursts from 20 kHz to 410 MHz
K. Sasikumar Raja, Milan Maksimovic, Eduard P. Kontar +10
We present the statistical analysis of the spectral response of solar radio type III bursts over the wide frequency range between 20 kHz and 410 MHz. For this purpose, we have used…
The population of M dwarfs observed at low radio frequencies
J. R. Callingham, H. K. Vedantham, T. W. Shimwell +12
Coherent low-frequency ( MHz) radio emission from stars encodes the conditions of the outer corona, mass-ejection events, and space weather. Previous low-frequency se…
Observations of shock propagation through turbulent plasma in the solar corona
Eoin P. Carley, Baptiste Cecconi, Hamish A. Reid +14
Eruptive activity in the solar corona can often lead to the propagation of shock waves. In the radio domain the primary signature of such shocks are type II radio bursts, observed…
