Triple

Given a phrase, classify it is english named entity (e.g., persons, organizations, works of art) in Latin script, or not (e.g., literals, dates, URLs, verbose phrases). For disambiguation, the statement where the phrase occurs as object is also given. Please return a JSON object with `phrase` (string, the phrase being analyzed) and `is_ne` (boolean, indicating whether the phrase is a Named Entity).

Phrase: Carter constant | Statement: [Brandon Carter, knownFor, Carter constant]

Target entity: Carter constant
Context triple: [Brandon Carter, knownFor, Carter constant]

• A. Euler–Mascheroni constant γ
  The Euler–Mascheroni constant γ is a mathematical constant that arises in analysis and number theory, defined as the limiting difference between the harmonic series and the natural logarithm.
• B. Gauss’s constant
  Gauss’s constant is a mathematical constant arising in number theory and complex analysis, particularly in connection with the lemniscate and elliptic functions.
• C. Eddington number
  The Eddington number is a dimensionless quantity in astrophysics that represents the maximum luminosity a star can have before radiation pressure overcomes gravitational attraction, leading to mass loss.
• D. Khinchin's constant
  Khinchin's constant is a mathematical constant that arises in metric number theory, describing the almost-sure geometric mean of the partial quotients in the continued fraction expansions of real numbers.
• E. Chaplygin C
  Chaplygin C is a small satellite impact crater on the Moon located near the larger Chaplygin crater on the lunar far side.
• F. None of above. chosen
• G. Unsure - the case is ambiguous/there is not enough information to decide.

You are given a context triple in the form (subject, predicate, object), where the object is the target entity. 
# Instructions
Use the triple to infer relevant information about the entity. Describe the entity based on what is most defining, well-known. 
Avoid repeating the information from the triple, unless really essential.
# Response Format
Return only the sentence: "Description: [one-sentence description of the target entity]"

Entity: Carter constant
Triple: [Brandon Carter, knownFor, Carter constant]

The Carter constant is a conserved quantity in general relativity that allows the complete integrability of geodesic motion in the Kerr spacetime around a rotating black hole.
