UNITED STATES.- An amazing discovery has been made known and it is nothing less than a new super earth located 36 light years from the Land and that it is orbiting very close to the cold dwarf star “GJ 740”. In this way, the discovery has been by Borja Toledo Padrón of the IInstitute of Astrophysics of the Canary Islands, generating great expectations among the scientific community.
In this context, it is worth noting that red dwarf stars have a temperature between 2,100 and 3,400 degrees Celsius and a mass of approximately 0.08 and 0.45 solar masses. In this way, this planet has an orbit of 2.4 days and has around 3 Earth masses and, due to its proximity to the Sun, this could begin to be a new source of study by specialists.
“We are facing the planet with the second shortest orbital period around this type of star. The mass and the orbital period of the planet suggest a rocky composition, as well as an estimated radius of 1.4 terrestrial radii, which can be confirmed with future observations ”, revealed the author of the discovery and member of the Canary Islands Astrophysics Institute (IAC), Borja Toledo Padrón.
In the same context, the data have also yielded the possible presence of a second planet orbiting for nine years and with a mass similar to Saturn (approximately 100 Earth masses). In addition, it was pointed out that its radial signal could have been caused by the star’s magnetic cycle, which is very similar to that which occurs with the Sun, and of course it takes more study time to be able to reach the origin of the signal.
Meanwhile, it is important to note that cold stars are an ideal target in the search for new planets by means of the radial velocity method; This is carried out based on the detection of variations in the speed of gravitational attraction exerted by the orbiting planets. So far (since 1998, which was the first signal captured), 116 exoplanets of these characteristics.
