Triple

Target class: self-gravitating fluid configuration
Context triple: [Roche–Riemann ellipsoids, instanceOf, self-gravitating fluid configuration]

• A. rotating fluid body chosen
  A rotating fluid body is a continuous mass of fluid that spins around an axis, whose shape, internal flow, and dynamical behavior are governed by the balance of inertial, gravitational, and pressure forces under rotation.
• B. rotational instability in stars
  Rotational instability in stars is a dynamical condition where differential rotation or excessive spin causes internal layers to become unstable, leading to mixing, angular momentum redistribution, and potentially large-scale structural changes or mass loss.
• C. astrophysical stability criterion
  An astrophysical stability criterion is a theoretical condition or set of conditions used to determine whether an astronomical system (such as a star, disk, or gas cloud) will remain in equilibrium or undergo collapse, fragmentation, or other dynamical instabilities.
• D. gravitational field model
  A gravitational field model is a conceptual representation that describes how mass generates a field influencing the motion and interaction of other masses through gravitational forces in space and time.
• E. gravitational collapse model
  A gravitational collapse model is a theoretical framework that describes how matter in astrophysical systems contracts under its own gravity, potentially leading to the formation of dense objects such as stars, black holes, or compact stellar remnants.
• F. None of above.
