Periodic Radio Emission from the T8 Dwarf WISE J062309.94–045624.6
The Astrophysical Journal Letters, 2023 We present the detection of rotationally modulated, circularly polarized radio emission from the T8 brown dwarf WISE J062309.94−045624.6 between 0.9 and 2.0 GHz.

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 ...

On the character and distribution of lower-frequency radio emissions at Saturn and their relationship to substorm-like events [PDF]
, 2009 With the arrival of the Cassini spacecraft at Saturn in July 2004, there have been quasi-continuous observations of Saturn kilometric radiation (SKR) emissions.

Study of nonthermal continuum patches : wave propagation and plasmapause study [PDF]
, 2011 Nonthermal continuum (NTC) radiation is believed to be emitted at the plasmapause and near the magnetic equator. We present a particular type of NTC radiation, referred to as NTC patch, which appears over a wide frequency range and within a relatively ...

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 ...
