Self-gravitation

rdf:langString Self-gravitation

rdf:langString Self-gravity is the gravitational force exerted on a body, or group of bodies, by the body/bodies that allows it/them to be held together. Self-gravity (self-gravitation) has effects in the fields of astronomy, physics, seismology, geology, and oceanography. Self-gravity differs with regards to the physical behavior on large scale (planet size or larger) objects, such as the oceans on Earth or the rings of Saturn. Lynden-Bell, a British theoretical astrophysicist, constructed the equation for calculating the effects of self gravitation. The equation's main purpose is giving exact descriptions of models for rotating flattened globular clusters. It is also used in understanding how clusters of stars interact with each other. Self-gravity deals with large-scale observations in fields outside of astronomy as well. Self-gravity does not typically appear as the central focus of scientific research, but understanding it and being able to include its effects mathematically increases the accuracy of models and understanding large-scale systems.
