StelleGravitation

StelleGravitation is a term used to describe the study of gravitational phenomena on and around stellar-scale structures, including how distributions of stars, stellar remnants, and gas influence spacetime and the dynamical evolution of systems. The concept is used in both scientific discussions and in science fiction to denote a field that combines elements of classical gravitation, general relativity, and emergent or quantum gravity ideas at or near stellar scales. In academic contexts, StelleGravitation is not universally recognized as a distinct, formal discipline; instead it is often treated as an interdisciplinary topic within astrophysics or gravitational theory, with definitions that vary by author.

Key topics include gravitational dynamics of star clusters and galactic nuclei, relativistic effects in high-density environments, and the interaction between gravity and stellar evolution. The approach uses analytical methods, numerical simulations such as N-body and relativistic hydrodynamics, and observational probes including stellar kinematics, gravitational lensing, timing of binary pulsars, and gravitational-wave signals.

Challenges and prospects involve linking small-scale gravity with global structures, reconciling quantum gravity ideas with stellar-scale physics, and testing predictions with data from telescopes and gravitational-wave observatories.
