Investigation of UV absorbers on Venus using the 283 and 365 nm phase curves obtained from Akatsuki

Y. J. Lee, A. García Muñoz, A. Yamazaki +3

The so-called unknown absorber in the clouds of Venus is an important absorber of solar energy, but its vertical distribution remains poorly quantified. We analyze the 283 and 365-…

Planetary-scale variations in winds and UV brightness at the Venusian cloud top: Periodicity and temporal evolution

Masataka Imai, Toru Kouyama, Yukihiro Takahashi +9

Planetary-scale waves at the Venusian cloud-top cause periodic variations in both winds and ultraviolet (UV) brightness. While the wave candidates are the 4-day Kelvin wave and 5-d…

The first astrophysical result of HISAKI: a search for the EUV He I lines a massive cool core cluster at z=0.7

Yuanyuan Su, Tomoki Kimura, Ralph Kraft +6

Molecular cold gas and star formation have been observed at centers of cool-core clusters, albeit at a level much smaller than expected from the classic cooling model. Feedback fro…

Long-term variations of Venus' 365-nm albedo observed by Venus Express, Akatsuki, MESSENGER, and Hubble Space Telescope

Yeon Joo Lee, Kandis-Lea Jessup, Santiago Perez-Hoyos +16

An unknown absorber near the cloud top level of Venus generates a broad absorption feature from the ultraviolet (UV) to visible, peaking around 360 nm, and therefore plays a critic…

Principal Components of Short-term Variability in Venus' UV Albedo

Pushkar Kopparla, Yeon Joo Lee, Takeshi Imamura +1

We explore the dominant modes of variability in the observed albedo at the cloud tops of Venus using the Akatsuki UVI 283-nm and 365-nm observations, which are sensitive to SO2 and…

Return to Venus of the Japanese Venus Climate Orbiter AKATSUKI

Masato Nakamura, Yasuhiro Kawakatsu, Chikako Hirose +19

Japanese Venus Climate Orbiter/AKATSUKI was proposed in 2001 with strong support by international Venus science community and approved as an ISAS (The Institute of Space and Astron…
