Direct Evidence of Drift‐Compressional Wave Generation in the Earth's Magnetosphere Detected by Arase

K. Yamamoto A. V. Rubtsov D. V. Kostarev P. N. Mager D. Yu. Klimushkin M. Nosé A. Matsuoka K. Asamura Y. Miyoshi S. Yokota S. Kasahara T. Hori K. Keika Y. Kasahara A. Kumamoto F. Tsuchiya M. Shoji S. Nakamura I. Shinohara

Geophysical Research Letters 51(8) 2024年4月

Abstract

We present the first direct evidence of an in situ excitation of drift‐compressional waves driven by drift resonance with ring current protons in the magnetosphere. Compressional Pc4–5 waves with frequencies of 4–12 mHz were observed by ...

Direct Observation of L‐X Mode of Auroral Kilometric Radiation in the Lower Latitude Magnetosphere by the Arase Satellite

Geophysical Research Letters 51(5) 2024年2月

Abstract

Previous studies have shown that auroral kilometric radiation (AKR) can play an important role in the magnetosphere‐atmosphere coupling and has the right‐handed extraordinary (R‐X), left‐handed ordinary (L‐O) and left‐handed extraordinar...

Long Lifetime Hiss Rays in the Disturbed Plasmasphere

Zhiyong Wu Zhenpeng Su Huinan Zheng Yuming Wang Yoshizumi Miyoshi Iku Shinohara Ayako Matsuoka Yoshiya Kasahara Fuminori Tsuchiya Atsushi Kumamoto Shoya Matsuda Yasumasa Kasaba Mariko Teramoto Tomoaki Hori

Geophysical Research Letters 51(4) 2024年2月

Abstract

Plasmaspheric hiss waves are important to shape the Earth’s electron radiation belt. These waves are commonly envisioned to have a long lifetime which allows them to permeate the global plasmasphere from a spatially restricted source. Ho...

Relativistic electron flux growth during storm and non-storm periods as observed by ARASE and GOES satellites

Vladimir Borisovich Belakhovsky Vyacheslav A. Pilipenko Elizaveta E. Antonova Yoshizumi Miyoshi Yoshiya Kasahara Satoshi Kasahara Nana Higashio Iku Shinohara Tomoaki Hori Shoya Matsuda Shoichiro Yokota Takeshi Takashima Mitani Takefumi Kunihiro Keika Satoko Nakamura

Earth, Planets and Space 75(1) 2023年12月

Abstract

Variations of relativistic electron fluxes (E ≥ 1 MeV) and wave activity in the Earth magnetosphere are studied to determine the contribution of different acceleration mechanisms of the outer radiation belt electrons: ULF mechanism, VLF ...
