The first exoplanet has been discovered by Subaru Strategic Program using the infrared spectrograph IRD on the Subaru Telescope (IRD-SSP). The mass of Ross 508b is about four times that of the Earth.
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 near the edge of the zone where life can exist. Scientists think that its path around the sun is elliptical. This planet might be able to support life.
This kind of planet might be able to keep water on its surface, and it will be an important place to look for life around low-mass stars in the future.
This artist’s sketch shows a close-up view of Proxima d, a planet candidate recently found orbiting the red dwarf star Proxima Centauri, which is the closest star to the Solar System. The planet is thought to be made of rocks and to weigh about a quarter as much as Earth. The image also shows two other planets that are known to orbit Proxima Centauri: Proxima b, which has about the same mass as Earth and orbits the star every 11 days and is in the habitable zone, and candidate Proxima c, which has a longer orbit around the star that takes five years.
Ross 508b will be an important place to look in the future to see if planets around red dwarfs could be habitable.
Spectroscopic observations of molecules and atoms in the planet’s atmosphere are also important. Since the planet is so close to the central star, current telescopes can’t take a direct picture of it.
“Because the planet is so close to the central star, current telescopes can’t take a direct picture of it. It will be one of the places where 30-meter-class telescopes look for life in the future, the team said.
