Mean winds at the cloud top of Venus obtained from two-wavelength UV imaging by Akatsuki
Imamura, Takeshi; Takagi, Masahiro; Yamazaki, Atsushi +9 more
Venus is covered with thick clouds. Ultraviolet (UV) images at 0.3–0.4 microns show detailed cloud features at the cloud-top level at about 70 km, which are created by an unknown UV-absorbing substance. Images acquired in this wavelength range have traditionally been used to measure winds at the cloud top. In this study, we report low-latitude win…
Initial products of Akatsuki 1-µm camera
Imamura, Takeshi; Ando, Hiroki; Ueno, Munetaka +25 more
The status and initial products of the 1-µm camera onboard the Akatsuki mission to Venus are presented. After the successful retrial of Venus' orbit insertion on Dec. 2015 (5 years after the failure in Dec. 2010), and after a long cruise under intense radiation, damage in the detector seems small and fortunately insignificant in the final qu…
Theory, modeling, and integrated studies in the Arase (ERG) project
Miyoshi, Yoshizumi; Saito, Shinji; Seki, Kanako +17 more
Understanding of underlying mechanisms of drastic variations of the near-Earth space (geospace) is one of the current focuses of the magnetospheric physics. The science target of the geospace research project Exploration of energization and Radiation in Geospace (ERG) is to understand the geospace variations with a focus on the relativistic electr…
Density response to magnetic field fluctuation in the foreshock plasma
Narita, Yasuhito; Hada, Tohru
The foreshock plasma exhibits large-amplitude disturbance in the plasma density and the magnetic field. The question of the density response to the magnetic field fluctuation is addressed and studied observationally and statistically using the in situ Cluster spacecraft data of the foreshock plasma. Three major findings are obtained. First, the de…
