Title: Extrasolar systems simulation
Post by frankuitaalst on 09/19/11 at 10:40:19

Hereunder is a simualtion of 25 extrasolar systems containing at least 3 extrasolar planets .
Data come from the extrasolar planets encyclopedia

In each system I've added an Earth like massless planet  at 1AU friom the central star , just for reference
I've aligned the 25 systems well spaced from each other .
You can jump from one system to another by selecting the "Sun" of the new system and center it

I had to make some assumptions : the inclination of each system is zero ; angle of perihelion is set to zero ; all planets were set at perihelion as initial value.

The systems in this sim are :
47 Uma
55 Cnc
61 Vir
Gl 581
Gliese 876
HD 10180
HD 125612
HD 134606
HD 136352
HD 181433
HD 20794
HD 31527
HD 37124
HD 39194
HD 40307
HD 69830
HIP 14810
HIP 57374
HR 8799
Kepler-11
Kepler-9
KOI-730
mu Ara
PSR 1257
ups And

I see there is a flaw in the KOI-730 system as I didn't pay attention on the position of two planets in this system which seem to be in resonance according to certain sources ( among others this forum )

Fixed the flaw .
Hereunder is the new sim .
KOI-730 is very interesting . It has two coorbital planets .
In order to find out : center on KOI-730 Sun , then goto rotating frame and choose rotating frame adjustment on KOI-730 c

KOI-730 has another solution. http://en.wikipedia.org/wiki/KOI-730

yes , right . It seems the coorbital solaution is abandonned .
