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

  • 自己重力（じこじゅうりょく）は、おもに天文学・天体物理学において星間雲や星の形成を議論する場合などに用いられる用語。星間雲や星の収縮はそれらを構成する物質自体の重力による。 万有引力の法則によれば、あらゆる物体は互いに引き合う力を生じるが、「質点同士に生じる重力」ではないことをより明確にするため自己重力と呼ばれる。 (ja)
  • 自我引力是指由一個或多個物體自己施加在自身上的重力，使該物體保持在一起。 自我引力在天文學，物理学，地震学，地质学和海洋学領域具有重要作用。 自我引力對於大型物體（行星或更大）的物理現象具有重要影響，例如地球上的海洋或土星環。 Lynden-Bell研究出計算自我引力的方程式，以提出對旋轉扁平球狀星團模型的精確描述，這是理解恒星團如何和每个恒星相互作用的關鍵。自我引力也能處理天文學以外领域的大規模观测。自我引力通常不會成為科學研究的焦點，但是了解自我引力可以提高模型的准确性和提升對於大型系统的了解。 (zh)

  • 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.

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.
