Title:
Remaining several issues on auroral process (and the RockSat rocket experiment)
Abstract:
I give a talk on a review of some recent subjects on auroral physics on the small-scale and the coupling to the global scale processes, and the current status of rocket experiment RockSat which will be launched in 2019.

タイトル:
オーロラ現象の残されたいくつかの課題(とRocksatロケット実験)
要旨:
オーロラ微細構造とグローバル現象とのマルチスケールカップリングなど、オーロラ現象の最新課題(ならびに2019年打ち上げ予定のRocksatロケット実験)について話します。

Title:
Radial variations of atomic oxygen number density in Io's neutral cloud
Abstract:
We report the spatial distributions of Io's oxygen neural cloud. Atomic oxygen and sulfur in Io's atmosphere escape from the exobase and move to neutral clouds (> 5.8 Io radii; Jupiter gravity is dominant) mainly due to atmospheric sputtering. Io plasma torus is formed by ionization of these atoms by electron impact and charge exchange processes. Therefore, The spatial distribution of oxygen and sulfur neutral clouds is important to understand the Io plasma source.
We carried out the monitoring of the azimuthal and radial distribution of atomic oxygen emission at 130.4 nm using Hisaki satellite. Observation period was November 25 - December 31, 2014 (35 days, volcanically quiet period). The results show the dense region of the oxygen neutral cloud is concentrated around Io and extends mainly toward Io and inside Io's orbit. In addition, the diffuse region uniformly exists along Io's orbit. Both components extend radially outward up to 7.6 Jupiter radii (RJ) with decreasing the density.
To use the previous studies of radial profile of electron density and temperature (< 5.9 RJ; Bagenal 1994, > 5.9 RJ; Yoshioka et al., 2017), We succeed to deduce the radial profile of oxygen atoms. In this presentation, we introduce the radial profile of atomic oxygen number density and oxygen plasma source rate.
