Observations of discrete e missions at the l ow l atitude g round station g ulmarg

TLDR
In this article, it was shown that these emissions are generated in the equatorial plane (L-1.2) by cyclotron resonance between the propagating wave and gyrating electrons.
Abstract
This paper presents discrete chorus type emissions observed in January/July, 1970 during the routine recording of whistlers and VLF emissions at our low latitude ground station Gulmarg (geomag. lat., 24 °26' N; geomag, long., 147°09 ' E). The chorus type emissions are comprised of discrete, sometimes overlapping, tones of one or more spectral shapes (risers, falling tones, hooks, etc.). It is shown that these emissions are generated in the equatorial plane (L-1.2) by cyclotron resonance between the propagating wave and gyrating electrons.

Electromagnetic hiss and relativistic electron losses in the inner zone. [of magnetosphere]

TL;DR: In this paper, the authors used pitch angle diffusion into the loss cone driven by the cyclotron resonant interaction to estimate the lifetime of inner-zone electrons, which ranges between 10 and 60 days.

Limit on stably trapped particle fluxes

TL;DR: The limit on stably trapped particle fluxes determined theoretically and compared with data from Explorer satellites was first established in this paper, and the limit was later confirmed by the International Journal of Astronautics.

Effects of Ions on Whistler-Mode Ray Tracing

TL;DR: In this paper, the Smith interpretation of the subprotonospheric whistler was confirmed, and it was found that an enhancement of electron density at the latitude of interest can support the ray path of the fractional hop as Smith suggested, as well as a possibility of successive echoes through a single path.

Magnetospheric chorus emissions : a review

TL;DR: In this paper, a review of chorus emissions observed on ground-based stations and in the Earth's magnetosphere is presented, where different approaches to modelling these emissions are discussed, and it is pointed out that the most likely energy source of the chorus emissions lies in the anisotropic hot electrons in the equatorial magnetosphere.

Electromagnetic hiss and relativistic electron losses in the inner zone

TL;DR: In this paper, it was shown that ELF hiss is present in the inner radiation zone (L less 2) during both storms and substorms, which is attributed to propagation of waves into this region from a distributed source located at high altitude near the equatorial plasmapause.
