Fast Litho-panspermia in the Habitable Zone of the TRAPPIST-1 System
With several short-period, Earth-mass planets in the habitable zone, the TRAPPIST-1 system potentially allows litho-panspermia to take place on very short timescales. We investigate the efficiency and speed of inter-planetary […]

UV Surface Habitability of the TRAPPIST-1 System
With the discovery of rocky planets in the temperate habitable zone (HZ) of the close-by cool star TRAPPIST-1 the question of whether such planets could also harbour life arises. Potentially […]
