Climate of high obliquity exo-terrestrial planets with a three-dimensional cloud system resolving climate model
Takanori Kodama, Daisuke Takasuka, Sam Sherriff-Tadano +4
Planetary climates are strongly affected by planetary orbital parameters such as obliquity, eccentricity, and precession. In exoplanetary systems, exo-terrestrial planets should ha…
A close-in puffy Neptune with hidden friends: The enigma of TOI 620
Michael A. Reefe, Rafael Luque, Eric Gaidos +82
We present the validation of a transiting low-density exoplanet orbiting the M2.5 dwarf TOI 620 discovered by the NASA TESS mission. We utilize photometric data from both TESS and…
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…
Inner Edge of Habitable Zones for Earth-sized Planets with Various Surface Water Distributions
Takanori Kodama, Hidenori Genda, Ryouta O'ishi +2
When planets receive insolation above a certain critical value called the runaway threshold, liquid surface water vaporizes completely, which forms the inner edge of the habitable…
Runaway climate cooling of ocean planets in the habitable zone: a consequence of seafloor weathering enhanced by melting of high-pressure ice
Akifumi Nakayama, Takanori Kodama, Masahiro Ikoma +1
Terrestrial planets covered globally with thick oceans (termed ocean planets) in the habitable zone were previously inferred to have extremely hot climates in most cases. This is b…
