The mass of a super-Earth is greater than that of the Earth. However, they are called extrasolar planets that are under the masses of Uranus and Neptune, the ice giants of the Solar System. Phase-fold curve of the RV time series using the GJ 740 b orbital period after subtracting the long-term signal and the rotation period. The vibration terms of each spectrograph were added to the original RV errors. The red solid line represents the planet pattern. The lower part represents the leftovers after removing the model.
Astronomers using the radial velocity (RV) technique have discovered a new super-Earth within the HADES and CARMENES programs. The new planet, called GJ 740 b, orbits a bright star about 36 light-years away. And at least three times bigger than Earth.
More than 600 exoplanets have been detected so far thanks to the radial velocity (RV) technique.
And 116 of them were found around the 'M' dwarfs. CARMENES , HADES and Calar Alto high resolution search for outer-world M dwarves; They were pivotal in the discovery of new outer-worlds orbiting these common stars in our galaxy.
A team of astronomers led by Borja Toledo-Padrón from the University of La Laguna in Spain reported that another external world was detected around a nearby M dwarf, known as the GJ 740. The HADES RV program monitored the GJ 740 at Telescopio Nazionale Galileo at the Roque de los Muchachos Observatory, Spain, using the installed HARPS-N spectrograph. Moreover, the spectra of this M dwarf were obtained by the CARMENES spectrograph at the Calar Alto Observatory, which coincided with the period when HARPS-N observations were carried out.
