Some stars and planets situations

An article published in the journal “Astronomy & Astrophysics” reports the discovery of an exoplanet candidate with a very high probability of existence, a super-Earth designated as KOI-456.04 whose estimated year is slightly longer than the Earth’s that orbits Kepler-160, a Sun-like star. A team of researchers led by RenĂ© Heller of the Max Planck Institute for Solar System Research in Göttingen, Germany, analyzed old data accumulated by the Kepler space telescope using a new method based on the detailed physical model of the stellar brightness variation instead of the classic one based on the search for the tiny drops in brightness that occur when the planet passes between the star and the telescope. The analysis also led to the discovery of another exoplanet candidate designated as Kepler-160 d.
