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…
