Scientists from the University of Technology of Swinburn and the University of Southern Queensland (Australia) named eight exoplanets, on whose satellites life can exist, and which are suitable for study by the ESPRESSO spectrograph (Echelle SPectrograph for Rocky Exoplanet and Stable Spectroscopic Observations).
In their work, scientists, based on the CELESTA (Catalog of Earth-like Exoplanet Survey Targets) catalog, searched for exoplanets that could have liveable satellites.
All these exoplanets are located in the zone of potential habitation of their luminaries and are gas giants, like Jupiter or Saturn. The existence of the moons near them has not been proved, scientists have selected those celestial bodies that, as satellites, can have earth-like stony objects located on stable orbits.
For example, one of these systems is located at star HD 43197 in the constellation Big Dog at a distance of 183 light years from Earth, in size and mass this luminary is comparable to the Sun. A HD 43197 b exoplanet revolves around HD 43197 about a light year with a period of about a year, which is 1.7 times lighter than Jupiter. The remaining seven stars are HD 87883, HD 164604, HD 156279, HD 285507, HD 80606, HD 162020 and HD 63454.
