Triple

Target class: ellipsoidal equilibrium configuration
Context triple: [Riemann ellipsoid, instanceOf, ellipsoidal equilibrium configuration]

• A. gravitational equilibrium point
  A gravitational equilibrium point is a location in space where the gravitational forces and orbital motion of a small object balance so that it can remain in a stable or semi-stable position relative to larger bodies.
• B. 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.
• C. 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.
• D. equilibrium figure chosen
  An equilibrium figure is the stable, self-gravitating shape a rotating fluid body (such as a star or planet) assumes when its internal forces—gravity, rotation, and pressure—are in balance.
• E. rotating fluid body
  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.
• F. None of above.
