![PANEL (A): Diagram of the net tidal accelerations acting on the planetary surface (caused by the host star’s gravity field). The planet is represented with a top view (i.e., as seen from above). Accelerations are computed in the reference frame of the planetary center. PANEL (B): Representation of the tidal bulge. The planet is represented with a top view. Planetary spinning (black arrow) is counterclockwise, as is the orbital motion around the star (red arrow). -- [astro-ph.EP]](https://i0.wp.com/astrobiology.com/wp-content/uploads/2026/08/Simulation.png?resize=1200%2C575&ssl=1)
[astro-ph.EP] In this work, using the simulator VPLanet, we analyze the spin evolution of some selected exoplanets due to the tidal interaction with their host star.

Superhabitability Of High-Obliquity And High-Eccentricity Planets
Planetary obliquity and eccentricity influence climate by shaping the spatial and temporal patterns of stellar energy incident at a planet’s surface, affecting both the annual mean climate and magnitude of […]
