How this entity was disambiguated
This entity first appeared as the object of triple T19173556 — resolving that mention is where its identity was fixed. The disambiguator weighed these candidate entities and picked the highlighted one (or “None”, minting a new entity). This is how homonymy is resolved: the same surface form can point to different entities.

-
A.
Bardeen potential
The Bardeen potential is a gauge-invariant gravitational potential used in cosmological perturbation theory to describe scalar metric fluctuations in the early universe.
-
B.
Roche ellipsoid
A Roche ellipsoid is an equilibrium shape assumed by a self-gravitating fluid body that is tidally distorted by a nearby massive companion, important in the study of close binary systems and tidal interactions.
-
C.
Roche–Riemann ellipsoids
Roche–Riemann ellipsoids are a family of rotating, self-gravitating fluid equilibrium figures in astrophysics and celestial mechanics that generalize classical ellipsoidal solutions like the Jacobi ellipsoid.
-
D.
Paczynski–Wiita potential
The Paczynski–Wiita potential is a pseudo-Newtonian gravitational potential used in astrophysics to approximate the effects of general relativity near non-rotating black holes while retaining the simplicity of Newtonian mechanics.
-
E.
Roche limit
The Roche limit is the minimum distance at which a celestial body, held together only by its own gravity, can orbit a larger body without being torn apart by tidal forces.
- F. None of above. chosen
- G. Unsure - the case is ambiguous/there is not enough information to decide.
