Rotating ellipsoidal variable
class of close binary variable star system
Rotating ellipsoidal variables are a class of close binary variable star systems whose components are ellipsoidal. They are not eclipsing, but fluctuations in apparent magnitude occur due to changes in the amount of light emitting area visible to the observer. Typical brightness fluctuations do not exceed 0.1 magnitudes.
The brightest rotating ellipsoidal variable is Spica (α Virginis).
Begin with the source’s own compact description: “Rotating ellipsoidal variable” is class of close binary variable star system. The dossier treats that line as a proposition to test through Rotating, ellipsoidal and variable, not as a finished interpretation.
Why this record matters
The phrase “class of close binary variable star system” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.
Vocabulary and entity names are the principal evidence signals here, because they determine the precision of every later search. The source revision retrieved here is dated Aug 19, 2026. The linked authority identifier is Q1332364. None of the 0 selected statements returned an explicit reference.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
