A team of astronomers discovers a new planet orbiting the sun barnard star, closest to our Sun and they do not rule out finding more exoplanets in other orbits of the star.
“We believe that Barnard’s star may have three more giant planets orbiting it, although for now we have indications that we cannot confirm,” explained the IAC researcher.
The data from the Discovery of the new world, Barnard b, and the Observations made during the last 5 years They were published Tuesday in the journal Astronomy & Astrophysics.
This is the world of ‘Barnard b’
Barnard b, the new world discovered, is located six light years from us and orbits in the star – each – Barnard, the closest to our Sun. What’s more, it has no oceans and has a very high temperature that makes life as we know it impossible.
The team is looking within the habitable zone, or temperate, zone of Barnard’s Star, where water can be found. However, they found this exoplanet, Barnard b, which is twenty times closer to Barnard’s star than Mercury is to the Sun.
Also, “he has a temperature of about 125ºC and an orbital period of 3.15 Earth days,” said Suárez Mascareño, according to ‘EFE’. “Even if the star is 2,500 degrees cooler than our Sun, It is too hot to drink liquid water on Earth’s surface,” adds the lead author.
No data from ‘Super-Earth’
To carry out this study, the team used Espresso, the most advanced instrument, according to ‘EFE’ and it was also confirmed by data from other instruments that are important in the search for exoplanets: HARPS, HARPS -N and CARMENES.
But what about Super-Earth reported in 2018? There is nothing. Barnard’s star, because of its proximity, is a target in the search for Earth-like planets but, since 2018, when a team of astronomers discovered the Super-Earth orbiting Barnard, no other planet has been made discovered in its orbit. It is a Super-Earth of 40% of Earth’s mass and with characteristics that make life as we know it impossible.
New data have not confirmed the existence and “at the moment the general consensus is that this exoplanet cannot exist,” Suárez Mascareño told EFE. Therefore, scientists and astronomers will continue to observe Barnard’s star.
