Tidal Heating of Exomoons In Resonance and Implications For Detection - Astrobiology

Maximum orbital periods of exomoons around 25 rocky planets that can potentially retain a moon for over 300 Myr (brown) and 85 Neptune-like planets that can retain a moon for over 5 Gyr (blue). The smallest maximum moon period is 10 days and the largest is 90 days. This stability range allows for placement of moons in a variety of 2:1 orbital configurations, like the 2d/4d periods we consider in this paper. The habitability of exoplanets can be strongly influenced by the presence of an exomoon, and in some cases the exomoon itself could be a possible place for life to develop. For moons outside of the habitable zone, significant tidal heating may raise their surface temperature enough to be considered habitable. Tidal heating of a moon depends on numerous …
