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.

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.

First Monitoring Campaign of a Main-sequence Radio Pulse Emitter: The Case of CU Vir

The Astrophysical Journal
CU Vir, a magnetic hot star, is the first discovered main-sequence radio pulse emitter (MRP) characterized by its ability to produce periodic radio pulses via electron cyclotron maser emission.

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 ...

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.

Rossby Number Regime, Convection Suppression, and Dynamo-generated Magnetism in Inflated Hot Jupiters

The Astrophysical Journal
Hot Jupiters (HJs) are commonly thought to host the strongest dynamo-generated magnetic fields among exoplanets, up to 1 order of magnitude larger than Jupiter. Thus, they have often been regarded as the most promising exoplanets to display magnetic star–

GMRT Survey of Radio Emission from Magnetic Massive Stars. I. Emission from Single Stars at Sub-GHz Frequencies

The Astrophysical Journal Supplement Series
With the growing subset of magnetic massive stars, it is now possible to conduct a systematic survey of radio emission from magnetic hot stars to better understand the underlying emission mechanisms.

Discoveries of Fine Structures and Secondary Pulses in Coherent Radio Emission from a Magnetic Massive Star

The Astrophysical Journal
In this paper, we report auroral radio emission from a magnetic B star HD 142990 using the MeerKAT radio telescope at 900–1670 MHz. This star is known to produce such emission (observed as periodic radio pulses) via electron cyclotron maser emission ...
