An article accepted for publication in “The Astrophysical Journal” describes a research on the exoplanet GJ 1132b, taken as an example of a rocky planet orbiting close to a red dwarf star. A team of astronomers led by Laura Schaefer of the Harvard-Smithsonian Center for Astrophysics (CfA) used computer models to simulate the evolution of that type of planet’s atmosphere concluding that could be thin and contain oxygen.
