I've been creating some star systems manually, but come across some issues with the orbits of some of the planets.
I've been letting the StarSolver figure out the orbital duration of the planets, but found that the orbit times have got crazy long.
One of the planets I put in (about 6000km and taken from a generated planet) has an orbit of 450000+ years, yet it's orbit is only 40 AU out.
At first I was thinking it was something to do with the Barycenter, but I'm now not so sure. Maybe I'm missing something. I use a Barycenter to create the relationship between a blackhole and red supergiant:
Star "Kalla B"
Class "M2 Ib" // spectral class "M1.5Iab-Ib"
Lum 9950.0 // luminosity, or
RadSol 720.5 // radius in Solar radii
MassSol 21 // mass in Solar masses
Teff 3650 // surface temperature in Kelvin
SemiMajorAxis 7.1 // in AU
Star "Kalla A"
Radius 0.00002 // in AU
Temperature 3000 // in Kelvin
Luminosity 250 // in Solar luminosities
Brightness 1 // render brightness scale
SemiMajorAxis 6.5 // in AU
Am I missing something. Betelgeuse is a comparable size (though a single star) and it's planets at 60AU orbits are between 100-200 years in length.I then noticed that the orbits around a red dwarf in the same system seem fine, so I'm assuming it's something to do with the way the gravitational pull of the supergiant and the black hole is calculated? Have I thrown off a variable?Can anyone point me in the direction of my mistakes?PS (thanks in advance)
