摘要: As evident from the nearby examples of Proxima Centauri and TRAPPIST-1, Earth-sized planets in habitable zone low-mass stars are common. Here, we focus on such planetary systems argue that their (oceanic) tides could be more prominent due to stronger tidal forces. We identify conditions under which may exert a significant positive influence biotic processes including abiogenesis, biological rhythms, nutrient upwelling stimulating photosynthesis. conclude our analysis with identification large-scale algal blooms as potential temporal biosignatures reflectance light curves can arise indirectly consequence strong
