Seven resonant planets around Trapist-1 star

This is an interesting remark, the behaviour of the planets can be modelled by choice of spin connection in non relativistic fluid dynamics. Then the planetary motion would cease to be Newtonian. Fluid dynamics should also be incorporated into the relativistic UFT377 in order to match theory and experimental data. The ground work for this has been done in UFT370 – UFT377. I am not sure that too much should be read from the ratios of orbits, but a choice of spin connection could result in some new music of the spheres.

In teh text the say that the planets are kept on their orbits by “nudges” that come from relics of the dust plane from which the planets have developed. This seems to be a type of fluid dynamics effect we can handle properly. The “resonances” are fixed ratios of their orbit periods. For example 3/2 is a musical fifth (quinta).

I think that this is a Newtonian explanation, the article does not define what is meant by “resonance” but it could easily be googled up. Any non Newtonian effects would be very small, and can now be understood with our new lagrangian method, which gives forward and retrograde precessions. This is not Euler Bernoulli resonance or spin connection resonance or any kind of resonance as usually meant in physics. Perhaps it is a journalistic term. The computer simulation would be an N body Newtonian simulation similar to molecular dynamics computer simulation. They play around with the input parameters to get a stable system.

Perhaps you might be interested in this information regarding possible explanations using resonance of the stability found in the Trapist-1 planet system.
