An article published in the journal “Nature Astronomy” reports the discovery of three exoplanets in the system of the red dwarf indicated in the research as TOI (Tess Object of Interest) 270 because it was studied using NASA’s TESS space telescope. They’re a super-Earth and two mini-Neptunes, all with orbits very close to their star. A team of researchers used observations made by TESS and follow-up observations with other telescopes to confirm the existence of the three exoplanets and provide some estimates of their characteristics, useful also because the two mini-Neptunes could provide information to understand the mechanisms of formation of planets of that type but also of rocky ones.

An article published in “The Astrophysical Journal Letters” reports the discovery of a gaseous exoplanet in the DS Tuc binary system thanks to the use of NASA’s TESS space telescope. A team of astronomers coordinated by Dartmouth College, New Hampshire, USA, conducted this research on the exoplanet named DS Tuc Ab, which has an estimated age of about 45 million years, a sort of preteen. It has completed its growth but it’s still in a phase in which changes take place, all useful information to understand the formation and evolution of the planets.
