HO-induced Greenhouse Warming on Oxidized Early Mars
Yuichi Ito, George L. Hashimoto, Yoshiyuki O. Takahashi +2
The existence of liquid water within an oxidized environment on early Mars has been inferred by the Mn-rich rocks found during recent explorations on Mars. The oxidized atmosphere…
Obliquity of an Earth-like planet from frequency modulation of its direct imaged lightcurve: mock analysis from general circulation model simulation
Yuta Nakagawa, Takanori Kodama, Masaki Ishiwatari +8
Direct-imaging techniques of exoplanets have made significant progress recently, and will eventually enable to monitor photometric and spectroscopic signals of earth-like habitable…
New constraint on the atmosphere of (50000) Quaoar from a stellar occultation
Ko Arimatsu, Ryou Ohsawa, George L. Hashimoto +35
We report observations of a stellar occultation by the classical Kuiper belt object (50000) Quaoar occurred on 28 June 2019. A single-chord high-cadence (2 Hz) photometry dataset w…
Global structure of thermal tides in the upper cloud layer of Venus revealed by LIR onboard Akatsuki
T. Kouyama, M. Taguchi, T. Fukuhara +11
Longwave Infrared Camera (LIR) onboard Akatsuki first revealed the global structure of the thermal tides in the upper cloud layer of Venus. The data were acquired over three Venusi…
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…
Lifetime and Spectral Evolution of a Magma Ocean with a Steam Atmosphere: Its Detectability by Future Direct Imaging
Keiko Hamano, Hajime Kawahara, Yutaka Abe +2
We present the thermal evolution and emergent spectra of solidifying terrestrial planets along with the formation of steam atmospheres. The lifetime of a magma ocean and its spectr…
