Golden law and Titius-Bode laws in the solar system

En résumé (grâce à un LLM libre auto-hébergé)

  • J.M. Souriau's work on the solar system shows a good correspondence between theoretical predictions and observed data.
  • The Golden Ratio and the Titius-Bode law are compared, with a graphical analysis of orbital distances on a logarithmic scale.
  • The satellites of Saturn and Jupiter are analyzed using a Fourier transform, revealing recurring peaks that allow prediction of their orbital periods.

a703 The work of J.M. Souriau on the solar system. (p: 2)
The theoretical prediction agrees well with the observed data, except for the resonant Neptune-Pluto pair, as expected.

What about the Titus-Bode law?

From the above theoretical result, Souriau immediately constructs a "golden law":
(a710) 1,9n

Next, the golden law is compared to the Titus-Bode law, which corresponds to: 2,4 (0,4 + 0,3 × 2n)

If we consider its rotation period, the Sun follows this law. The interpretation is as follows: Souriau assumes that the entire system is shaped by dissipative processes due to tidal effects.

Then, he applies his method to the satellites of Saturn:

Two characteristic peaks appear again. Selecting these two lines, Souriau constructs the reciprocal Fourier transforms. The result is shown in figure 7. Note that the Sun "behaves like a satellite of Saturn".

By the way, Saturn's rings fit very well the golden law.

Similar results for the set of Jupiter's satellites.

Note the presence of the Sun, considered as "a satellite of Jupiter".
