Triple

Target class: theory of rotating self-gravitating fluids
Context triple: [Chandrasekhar’s theory of ellipsoidal figures of equilibrium, instanceOf, theory of rotating self-gravitating fluids]

• A. 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.
• 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. result in angular momentum theory
  A result in angular momentum theory is a formal statement or theorem that characterizes how angular momentum operators, their eigenvalues, and associated quantum states behave and combine under rotations and symmetry transformations.
• D. 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.
• E. system of coupled field equations chosen
  A system of coupled field equations is a set of interdependent mathematical relations describing how multiple fields evolve together in space and time, each influencing and being influenced by the others.
• F. None of above.
