Revisiting the greenhouse effect of non-greenhouse gases in the atmospheres of Earth-like planets
Tetsuo Taki, Hiroyuki Kurokawa, Yuka Fujii +1
Although non-greenhouse gases can vary substantially in abundance in Earth-like atmospheres, their climatic influences remain insufficiently understood. To investigate how such gas…
Tempawral: A Time-Resolved Retrieval Framework for Variable Brown Dwarfs and Exoplanets
Fei Wang, Ben Burningham, Stuart Littlefair +4
Brown dwarfs and exoplanets are thought to host complex atmospheric phenomena such as clouds, storms, and chemical heterogeneity, akin to weather patterns on Earth. These features…
On the synergetic use of Ariel and JWST for exoplanet atmospheric science
Quentin Changeat, Pierre-Olivier Lagage, Giovanna Tinetti +27
This paper explores the potential for strategic synergies between the JWST and the Ariel telescopes, two flagship observatories poised to revolutionise the study of exoplanet atmos…
Probing thermal gradients of habitable-zone rocky planets as an anti-indicator of a global surface ocean using mid-infrared direct imaging
Yuka Fujii, Daniel Angerhausen, Taro Matsuo +1
Future direct-imaging missions such as the Large Interferometer for Exoplanets (LIFE) aim to observe thermal emission from potentially habitable planets to characterize their surfa…
Impacts of Atmospheric Carbon Species and Stellar Type on Climates of Terrestrial Planets
Jared Landry, Hiroyuki Kurokawa, Tetsuo Taki +3
The climates of terrestrial planets are largely determined by the composition of their atmospheres and spectral types of their host stars. Previous studies suggest a wide range of…
Monosilane Worlds: Sub-Neptunes with Atmospheres Shaped by Reduced Magma Oceans
Yuichi Ito, Tadahiro Kimura, Kazumasa Ohno +2
High-precision infrared spectroscopic measurements now enable detailed characterization of sub-Neptune atmospheres, potentially providing constraints on their interiors. Motivated…
