Dynamical models are mathematical representations that describe the time-dependent evolution of a system's state through differential equations or numerical simulations. These models are crucial in understanding how the gravitational interactions between celestial bodies influence their movements and behaviors, especially in systems with multiple objects like exoplanets and their host stars. By analyzing these interactions, scientists can predict phenomena such as transit timing variations, which are deviations in the timing of a planet's transit across its star due to gravitational perturbations from other bodies in the system.
congrats on reading the definition of Dynamical Models. now let's actually learn it.
