Jupiter - friend or foe?
02/08/12 at 04:33:13
 
http://arxiv.org/abs/1202.1314 - very interesting reading!
 
I wonder if this nu6 resonance shows up in gravsim runs. I think I might have run into it while I was playing around with my asteroid belt sims a few years ago...?

It's a secular resonance, so you'll need to output some data to Excel to find it.  You need to create a column that tells you the rate at which the orbits are precessing, and look for a match.

20 years of computer time ! Amazing .  
I wonder what is meant with v6 ( nu6 ) secular resonance ? Can somebody explain ?

I found this definition at http://www.oca.eu/morby/ESA/dictionary.html#nu6 , which isn't entirely clear
 
Quote:
nu6 resonance:
Resonance that occurs when the precession frequency of the asteroid's longitude of perihelion is equal to the sixth secular frequency of the planetary system. The latter is related to the mean precession frequency of Saturn's longitude of perihelion, but it is also relevant in the secular oscillation of the eccentricity of Jupiter.

 
It's shown nicely in the graph here though:

Apparently a lot of NEOs come from that region of the asteroid belt.

Thanks for the info EDG  .  
Have you tried the "animation" in this ?  
http://www.oca.eu/morby/ESA/methodology.html  
Gives an idea how bodies spread out , similar as you did some time ago
