The researchers were able to detect the planet thanks to the IRD infrared spectrograph on the Subaru Telescope (IRD-SSP).
The device captures even the smallest fluctuations in the radial velocity of stars, according to an article published in the journal Publications of the Astronomical Society of Japan.
The exoplanet is located on the inner edge of the habitable zone. Scientists suggest that it has an elliptical orbit. This is a potentially habitable planet.
Such a planet may be able to retain water on its surface, and will be an important target for future observations to verify the possibility of life around low-mass stars.
Ross 508b will be an important target for future observations to verify the possibility of habitability on planets around red dwarfs.
Spectroscopic observations of molecules and atoms in the planetary atmosphere are also important, while the current telescopes cannot directly image the planet due to its closeness to the central star.
“While the current telescopes cannot directly image the planet due to its closeness to the central star. In the future, it will be one of the targets of life searches by 30-meter class telescopes,” the team said.
