Discussion Overview
The discussion revolves around the determination of the constant K for a relativistic star with a polytropic index of n=3, as derived from the mass-radius relation. Participants seek clarification on the symbols used and the connection between pressure and density in this context.
Discussion Character
- Technical explanation, Conceptual clarification, Debate/contested
Main Points Raised
- One participant presents a mass-radius relation for a relativistic star and requests information on the value of K for n=3.
- Another participant asks for clarification on the symbols used, specifically questioning the meanings of n, k, K, and M3.
- A participant confirms that n is the polytropic index, k is the constant relating pressure and density, and M3 refers to the mass of the star.
- Concerns are raised about the consistency of notation, particularly the distinction between k and K, and the non-standard use of M3.
- One participant suggests that the original poster refer to Wikipedia for insights on the origin of K.
- A later reply indicates that a simple algebraic manipulation could relate the participant's K to the notation used in Wikipedia.
Areas of Agreement / Disagreement
There is no consensus on the value of K or its derivation, and participants express differing views on the clarity of notation and definitions.
Contextual Notes
Participants note the need for consistent notation and the potential for confusion arising from non-standard symbols. The discussion does not resolve the specific value of K or its derivation.
