Revealing the dynamics of magnetosphere, atmosphere, and interior of solar system objects with the Square Kilometre Array
Tomoki Kimura, Yuka Fujii, Hajime Kita +3
Bodies such as planets, moons, and asteroids in our solar system are the brightest objects in the low-frequency radio astronomy at 10 GHz. The low-frequency radio emissi…
Next Generation of Telescopes or Dynamics Required to Determine if Exo-Moons have Prograde or Retrograde Orbits
Karen M. Lewis, Yuka Fujii
We survey the methods proposed in the literature for detecting moons of extrasolar planets in terms of their ability to distinguish between prograde and retrograde moon orbits, an…
Some inconvenient truths about biosignatures involving two chemical species on Earth-like exoplanets
Hanno Rein, Yuka Fujii, David S. Spiegel
The detection of strong thermochemical disequilibrium in the atmosphere of an extrasolar planet is thought to be a potential biosignature. In this article we present a new kind of…
Can Ground-based Telescopes Detect The Oxygen 1.27 Micron Absorption Feature as a Biomarker in Exoplanets ?
Hajime Kawahara, Taro Matsuo, Michihiro Takami +5
The oxygen absorption line imprinted in the scattered light from the Earth-like planets has been considered the most promising metabolic biomarker of the exo-life. We examine the f…
Global Mapping of Earth-like Exoplanets from Scattered Light Curves
Hajime Kawahara, Yuka Fujii
Scattered lights from terrestrial exoplanets provide valuable information about the planetary surface. Applying the surface reconstruction method proposed by Fujii et al. (2010) to…
