An international group of scientists from the UAE and the United States found out which double stars systems can have potentially suitable planet. The conclusions of astronomers are published in the log of Frontiers in Astronomy and Space Sciences. Briefly about scientific work reports the Edition of Science Alert.
Researchers analyzed the data collected by the Kepler space telescope, about nine planetary systems: Kepler-16, Kepler-34, Kepler-35, Kepler-38, Kepler-64, Kepler-413, Kepler-453, Kepler-1647 and Kepler -1661. The parameters such as the mass of stars, their brightness, as well as the remoteness of the exoplanets from its sun were taken into account. To test the potential habitability of exoplanets used previously derived equations, and not modeling that could take longer.
It turned out that the presence of a giant planet in most of the systems considered does not exclude the existence of potentially inhabitable worlds. KEPLER-16 and KEPLER-1647 contain gas giants that are unsuccessfully located to create a stable zone of habitability – areas in space in which planets get enough heat from the star so that water on them existed in the liquid phase. However, KEPLER-34, KEPLER-35, KEPLER-38, KEPLER-64 and KEPLER-413 may be suitable for the existence of the planet’s life, while the most favorable are KEPLER-35, -38 and -64.
However, there is another limitation – the stability of the orbit of the exoplanet itself. If the planet comes out of the habitability zone, its oceans can throw out or freeze together with the atmosphere. According to astronomers, if they determine the planets with a suitable orbit, then in the future it will be possible to calculate how much light radiation they get from parental stars.
