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

A model of so-called "Zebra" emissions in solar flare radio burst continua [PDF]
Annales Geophysicae, 2011 A simple mechanism for the generation of electromagnetic "Zebra" pattern emissions is proposed. "Zebra" bursts are regularly spaced narrow-band radio emissions on the otherwise broadband radio continuum emitted by the active solar corona.

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 ...

Probing discrete auroral arcs by ionospheric tomography [PDF]
Annales Geophysicae, 1998 Optical observations of 557.7 nm and 630.0 nm emissions from discrete auroral arcs in the post-noon sector have been related to localised field-aligned enhancements in the spatial distribution of E- and F-layer electron density respectively seen in ...

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 ...

The Astrophysical Journal, 2023 Although the majority of hot magnetic stars have extremely stable, ∼kilogauss strength surface magnetic fields with simple topologies, a subset undergoes small-scale explosions due to centrifugal breakout.
