Modeling the transport and anisotropy of energetic electrons in solar flares

Frontiers in Astronomy and Space Sciences
Transport of energetic electrons in the flare loop is important to understanding nonthermal emissions in solar flares. In this work, we model the propagation of electrons by numerically solving the particle transport equation which includes the physics ...

Radio Prospects of Extrasolar Aurorae Polaris as a Probe of Planetary Magnetism

The Astrophysical Journal
Magnetized exoplanets are expected to emit auroral cyclotron radiation in the radio regime due to the interactions between their magnetospheres, the interplanetary magnetic field, and the stellar wind.

Terrestrial kilometric radiation: 1: Spatial structures studies [PDF]

Observations are presented of lunar occultations of the earth at 250 kHz obtained with the Radio-Astronomy-Explorer-2 satellite which were used to derive two dimensional maps of the location of the sources of terrestrial kilometric radiation (TKR).

Generation of Electromagnetic Ion Cyclotron Wave by Hot Injection of Ion Beam for Ring Distribution with A.C. Electric Field in Jovian Magnetosphere

East European Journal of Physics
This paper investigates the electromagnetic ion-cyclotron waves detected by the Ulysses spacecraft within the Jovian magnetosphere. Various types of high-frequency radio emissions resulting from resonant interactions have been identified in this region ...

Scattering of terrestrial kilometric radiation at very high altitudes [PDF]

On a number of occasions during the 3.8 yr. operating lifetime of RAE-2, strong terrestrial kilometric radiation was observed when the spacecraft was over the far side of the moon and when the low altitude terrestrial magnetosphere was completely ...

Nonlinear Alfvén-wave Dynamics and Premerger Emission from Crustal Oscillations in Neutron Star Mergers

The Astrophysical Journal Letters
Neutron stars have solid crusts threaded by strong magnetic fields. Perturbations in the crust can excite nonradial oscillations, which can in turn launch Alfvén waves into the magnetosphere.

A Volume-limited Radio Search for Magnetic Activity in 140 Exoplanets with the Very Large Array

The Astronomical Journal
We present results from a search for radio emission in 77 stellar systems hosting 140 exoplanets, predominantly within 17.5 pc using the Very Large Array (VLA) at 4–8 GHz.
