Tidally driven tectonic activity as a parameter in exoplanet habitability

Aims. On Earth, plate tectonics play an integral role in driving the long-term carbon cycle; however, on tidally locked rocky exoplanets alternative tectonic mechanisms driven by tidal stress and heating could serve analogous way. Methods. We calculate rates to model likelihood of activity maintaining stable climates suitable for surface liquid water with radii ${R}_{p}$ $\le$ 1.23R$_\oplus$. Results. Applying models our sample 767 reveals that $\sim$10% exoplanets, including Proxima Cen b GJ 1061 d from circumstellar habitable zone (CHZ), pass subduction threshold mobile lid reside within optimal zone. This subset sustain induced temperate comparable aiding presence water. Furthermore, $\sim$40% located CHZ would be unable maintain needed stabilise climate are unlikely retain When broadening modelling establish overlap between stress, heating, CHZ, discover regions target future observations, we determine conducive maintenance occurs predominantly around M dwarfs, identify intersections, where both sustained eccentric (e>0.1) Earth-sized (${R}_{p}$ = 1.0-1.23R$_\oplus$) orbiting low-mass dwarfs.
