An article published in the journal "Monthly Notices of the Royal Astronomical Society" (MNRAS) reports the discovery of a rare hierarchical quadruple system, which was cataloged as UPM J1040−3551 AabBab. A team of researchers used various observations to identify this quartet consisting of a pair of red dwarfs and a pair of brown dwarfs.
Our galaxy is a jewel box of red stars. More than 70% of the stars in the Milky Way are M dwarfs, also known as red dwarfs. These stars are cool and dim compared with our Sun, but they often blast orbiting exoplanets with high-energy radiation, especially early in their lives. And those ‘‘lives’’ last […]
Predicting ‘#Earth-like’ #planets around #reddwarfs | #NatureAstronomy
The Earth is a rocky planet in the so-called classical habitable zone (HZ), with a surface ocean taking up just ~10–4 of its total mass. A study suggests that 5–10% of Earth-sized planets in the HZ around red dwarfs are ‘Earth-like’: rocky, with a small but non-zero amount of water on their surface.
