A joint group of astrophysicists from Princeton, the University of Michigan and Harvard, during the study, concluded that the aquatic worlds could become uninhabited 1 billion years after birth. This is due to the fact that the planets cannot hold water for a long time.
Led by Chuanfei Dong of the Department of Astrophysical Sciences at Princeton University, the team conducted computer simulations that took into account the conditions in the aquatic world for life. This study was motivated by the large number of exoplanetary discoveries that have been made around low-mass M (red dwarf) stellar systems in recent years.
During the study, scientists investigated the effects of stellar magnetic fields, coronal mass ejections and atmospheric ionization, ejection for various types of stars, including type G stars (for example, our Sun) and M-type stars (such as Proxima Centauri and TRAPPIST-1). Based on these experiments, scientists have developed a model that shows the lifespan of the atmosphere of exoplanets. Astrophysicists have found that previous models were based on the Earth-Sun principle, but the behavior of planets in different systems can differ significantly.
According to the results of the experiments, scientists determined that the planets on which there is a large amount of water cannot be a place for life, since the ions in them have low emission, which indicates the absence of conditions for the emergence of organisms.
