Astrophysics Stellar Oscillation3 From Jcost P Mode3 Cert

A machine-checked certificate named pMode3Cert proves three general properties of a cost function, but its name does not turn those properties into a statement about stars.

What pMode3Cert actually proves

In the Recognition Science framework, a ledger is a discrete record of events, and the cost of recognizing an event is a number that measures how far a ratio is from unity. The declaration pMode3Cert is a small machine-checked structure in the framework's library of formal theorems. It bundles three facts about the cost function applied to a ratio m/e, where m and e are positive real numbers.

The three facts are these. First, when m equals e, the cost is exactly zero. Second, for any positive m and e, the cost is never negative. Third, the number phi minus 3/2 is positive, where phi is the golden ratio. Each fact is proved in the framework's library, and the certificate simply assembles them into one object. The name pMode3Cert suggests a connection to stellar oscillations, specifically to the large frequency separation of pressure-mode oscillations in a star like the Sun.

The library's own documentation is explicit about the limit. The module proves nothing specific to stellar physics, because the cost function is defined as Jcost (m / e) without any reference to a star, a mode, or a frequency. The connection to asteroseismology is a research note, not a result. The note records an intended direction: the observed solar large frequency separation of about 135 microhertz is compared with powers of phi times 10 microhertz, and phi to the fifth power times 1.22 gives 135. That comparison is an empirical observation, not a theorem.

What pMode3Cert establishes, then, is a general mathematical fact about the cost function, available for any domain where m and e can be defined. What it does not establish is any statement about the Sun, about stellar structure, or about the physical mechanism behind oscillation frequencies. The certificate is a template waiting for a subject-specific definition of m and e; without that definition, it remains a statement about real numbers.

What this page does not claim

pMode3Cert does not prove that the Sun's oscillation frequencies follow a phi-power law. The certificate does not establish any physical mechanism for the large frequency separation. The numerical comparison with 135 microhertz is an empirical note, not a derived result.

Verify this page

Every tagged claim above names its theorem. To check one yourself rather than trust this page, elaborate the source module with Lean 4 and audit its axiom basis:

expected axiom basis: [propext, Classical.choice, Quot.sound] (the Lean kernel's standard three; no RS-specific axioms)

A page whose claims cannot be reproduced this way does not ship. In production, every anchor links to the exact declaration in the public source release, and this block carries the build receipt for the page itself.
