Radio Emission and Electric Gaps in Pulsar Magnetospheres
The Astrophysical Journal Letters, 2023 Abstract The origin of pulsar radio emission is one of the old puzzles in theoretical astrophysics. In this Letter, we present a global kinetic plasma simulation that shows from first principles how and where radio emission can be produced in pulsar magnetospheres.

Radio emission in Mercury magnetosphere [PDF]
Astronomy & Astrophysics, 2016 Context: Active stars possess magnetized wind that has a direct impact on planets that can lead to radio emission. Mercury is a good test case to study the effect of the solar wind and interplanetary magnetic field on radio emission driven in the planet magnetosphere. Such studies could be used as proxies to characterize the magnetic field topology and

Radio emission altitudes in pulsar magnetospheres [PDF]
Monthly Notices of the Royal Astronomical Society, 1997 A geometrical analysis of the pulse-profile widths at 0.43 and 1.42 GHz (Arecibo) as well as at 1.41 GHz (Effelsberg) is presented. We have measured the profile pulse widths at the lowest possible intensity level. An empirical relationship for the pulsar radio emission altitudes is proposed. We argue that for the millisecond pulsars the emission region

Radio emission from mini‐magnetospheres on the Moon [PDF]
Geophysical Research Letters, 2004 Small‐scale, localized magnetic anomalies on the surface of planetary satellites effectively create “mini‐magnetospheres”, which can lead to standoff shocks analogous to planetary bow shocks. This gives rise to the tantalizing possibility that radio emission can be produced in the vicinity of such mini‐magnetospheres, since it is well known that radio ...

VLF-LF Radio Bursts Observed at Local Onsets of Magnetospheric Substorms
Antarctic Record, 1976 Observations of VLF hiss narrow-band intensities (5.0±0.2 kHz, 12.0±0.5 kHz, and 50.0±1.0 kHz), horizontal component (H) of the geomagnetic field, and the ionospheric absorption of cosmic radio noises of 30 MHz have been carried out at Syowa Station ...

Cassini in situ observations of long duration magnetic reconnection in Saturn’s magnetotail [PDF]
, 2015 Magnetic reconnection is a fundamental process in solar system and astrophysical plasmas, through which stored magnetic energy associated with current sheets is converted into thermal, kinetic and wave energy1, 2, 3, 4.
