From our Earth-Moon duo to the outer edge of the solar system and beyond, tidal interactions play a prominent role in dictating the long-term evolution and fate of planetary systems. Underpinned by different physical mechanisms, often complicated ones, the relatively small and slow reciprocal tidal effects accumulate to cause significant signatures among the tidal players: orbital and rotational dynamical variations, periodic bodily deformations, heating due to energy dissipation, and climatic effects, to name a few. Some of these signatures are directly detectable, as is the case in seismic, geodetic, astrometric, and remote sensing analyses of several solar system objects; while others are modeled to study the orbital architecture and potential habitability of exosystems.

Despite the ubiquitous nature of these tidal interactions, the underlying physical processes and the often-used tidal models are still poorly constrained. A deeper understanding of both fluid and solid physical tidal phenomena, along with a macroscopic view on the observational end, and a discussion on the implementation of different tidal models and their mathematical frameworks are thus required.

This session aims to bring together both solar system and exo-planetary scientists into a cohesive discussion on multidisciplinary aspects of tidal interactions, be it solid, oceanic, or atmospheric, and their various rich signatures. We invite presenters to showcase their recent contributions of theoretical, observational, and modeling nature (or a combination thereof).
