The team from Spain, Italy and Germany discovered a super Earth, a giant planet with the same makeup as the planet, located just 36.2 light years from us.
The new Super Earth revolves around a bright red M1-type dwarf star named Gliese 740, in the constellation Serpens. It is very rare to spot a planet orbiting red dwarfs, as their light is much worse than that of other types of stars, so the planets around them hide in dark areas.
Speaking on Sci-News, Dr Borja Toledo-Padrón of the Canary Islands Astronomical Institute (Spain) said he carefully analyzed indicators of chromatographic activity in the dark region around the red dwarf to eliminate false planetary signals . The new planet has since been clearly revealed thanks to 32 spectral data from the CARMENES spectrometer located at the HARPS-N Observatory, which is a planet-finding system based on dark radial speed technology. .
From the southern hemisphere, the HARPS spectrometer located at the La Silla Observatory (located in Chile) also validates the data. The discovery is part of a program called HADES that their team is pursuing, specializing in exploring the world around red dwarfs.
The study is about to be published in Astronomy & Astrophysics that the new super-Earth Gliese 740b has a mass three times our planet, a radius of about 1.43 times. It revolves around the star every 2.4 days with a distance of only 0.03 astronomical unit (1 astronomical unit is the distance from the Sun to Earth).
This very small distance has brought super Earth a “hellish” temperature: up to 556 degrees Celsius and possibly no living organism. At a distance of 36.2 light years, it is one of the closest super-Earths ever discovered.
