The authors of the new study presented the main list for the search for habitable exomoons, it was published in
Scientists have not yet found real exomoons, so they investigated the habitability of hypothetical exomoons that may orbit known exoplanets, the authors say.
Although no one is known todayexomoons, their potential habitability is an interesting and important question, the authors write. The researchers published a list of targets to maximize the chances of finding potentially habitable objects.
Research focused on large rockyexomoons that can create an atmosphere. The authors also studied the temperature of such objects depending on the distance from the star. They didn't take into account radiogenic heating, which could provide enough heat to keep a subsurface ocean like Europa and Enceladus.
As a result, the authors received 4,140 knownexoplanets. For each of these planets, they modeled 100,000 moons. And calculated the probability of habitability for each simulated moon. The researchers have created a table of exoplanets that are likely to host potentially habitable satellites.
Kepler-459 b is the most likely planetformation of habitable exomoons. This is Subupiter, orbiting a star like our sun every 854 days. The probability of habitability of the exomoon Kepler-459 b is 70%.
Kepler-456 b is also a sub-Jupiter, orbiting a star about the same mass as the Sun, but with an orbit of 1,320 days. The probability of habitability of the exomoon Kepler-456 b is 69%.
Third on the list is HD 7199 b. It is a gas giant that orbits its sun-like star every 1.7 years. The probability of habitability of the exomoon HD 7199 b is 64%.
