cds-question@unistra.frmultiple-starsexoplanetsHabitability of an exoplanet is defined by its ability to support surface liquid water. The long-term carbon cycle plays an important role in regulating planetary temperature, thus aiding the conditions for the preservation of surface liquid water and,consequently, the habitability of exoplanets. 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 tidal heating could serve in an analogous way. We calculate tidal stress and tidal heating rates to model the likelihood of tectonic activity maintaining stable climates suitable for surface liquid water on tidally locked rocky exoplanets with radii Rp<=1.23R_{Earth}_. Applying the tidal models to our sample of 767 tidally locked rocky exoplanets reveals that ~10% of exoplanets, including Proxima Cen b and GJ 1061 d from the circumstellar habitable zone (CHZ), pass the tidal stress subduction threshold for mobile lid tectonic activity and reside within the optimal tidal heating zone. This subset of exoplanets could sustain tidally induced temperate mobile lid tectonic activity comparable to plate tectonics on Earth, aiding in maintaining the presence of surface liquid water. Further-more, ~40% of exoplanets from our sample located in the CHZ would be unable to maintain the tectonic activity needed to stabilise the climate and are unlikely to retain surface liquid water. When broadening our modelling to establish the overlap between tidal stress, tidal heating, and the CHZ, to discover optimal regions to target for future observations, we determine that tidally driven tec-tonic activity conducive to the maintenance of surface liquid water occurs predominantly around M dwarfs, and identify intersections,where both mobile lid and optimal tidal heating could be sustained on eccentric (e>0.1) Earth-sized exoplanets (Rp=1.0-1.23R_{Earth}_)orbiting in the CHZ of low mass M dwarfs.2022A&A...662A..15Mhttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/A+A/662/A15CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/A+A/662/A15https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/A+A/662/A15http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/A+A/662/A15https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/A+A/662/A15https://vizier.iucaa.in/viz-bin/votable?-source=J/A+A/662/A15http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/A+A/662/A15GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/A+A/662/A15/table1 (767 tidally locked rocky exoplanets)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/A+A/662/A15/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/A+A/662/A15/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/A+A/662/A15/table1?GETtext/xml+votable180.050000true286.142877243.23633330.0055555555555555564/935 946 5/3646 3688-3689 3691 3706 3730-3733 3736 3739 3776-3778 3780 3782-3783 3788 3792 6/250 353 404 449 1036 1064 4330 4345 4662 4716 10061 14573 14575 14578-14579 14582-14583 14589-14591 14733-14735 14744 14746 14750-14751 14761-14763 14768-14770 14772 14774-14775 14777-14779 14781-14783 14792 14794 14816-14817 14828 14830 14915 14917-14919 14936 14938-14942 14948 14950-14951 14954-14955 15040-15041 15043-15044 15057 15059-15062 15116-15118 15124-15126 15157-15161 15172 15174 15178 15200 15232 16094 16472 16758 16847 17425 18029 18033 18435 18455 18491 18582 18585 18627 18641 18726 22309 22645 25312 25423 25463 25552-25553 25631 25810 26256 26297 26972 26992 27072 27093 27121 27392-27393 27411 27690 27777 29349 30771 33210 33972 34005 34448 34561 35954 36555 36614 37453 37548 38456 38464 39080 39148 40250 41591 44921 45964 48098https://cdsarc.cds.unistra.fr/viz-bin/moc/J/A+A/662/A15?format=asciidefaultJ/A+A/662/A15/table1767 tidally locked rocky exoplanetsSimbadNameSimbad column added by the CDSmeta.idcharnullablerecnoRecord number assigned by the VizieR team.
