Orbital perturbations?

Interesting system here, Byoomao UZ-F d11-8133. Could be a good test of stellar forge's orbital dynamics, whether it includes osculating orbits or perturbations. That's if anyone has the patience to come up with a methodology for measuring the system over time that doesn't become too time consuming in itself!


Because of the eccentric orbit of the primaries, the K dwarf’s distance from the first planet will change by as much as the planet’s own orbit radius! Closest approach is just under 900 ls. The neutron star, of course, stays a little closer to home.

Animated style below, just to give a better sense of it.

It doesn't. The star systems are static and objects orbit 'on rails'. The only thing able to change orbital parameters is FDev messing with the game directly.

That was my suspicion, especially since any real perturbations at all are likely to not allow a system like this one.

Osculating orbits on the other hand use equations which produce the usual 6 orbital elements, several of which change over time, and often in cycles. Better than just 6 constants, but not as accurate as n-body perturbation. So I suppose this thread is clickbait in a way

The way stellar forge produces systems is surprisingly robust IMO. Most (definitely not all) of the flaws I think are rooted in the way the game classifies and handles what stellar forge gives it. Like the gas giants that are hotter than stars but give off no heat, or a brown dwarf that will cook you at 300 K (nope I'm not missing a zero!), or just the way a discovery scanner (sort of) gives you total knowledge of what you'll find before you get there. Hell even black holes are harmless in the game. You can drive into one in normal space and you just get stopped before getting too close!

It seems to me that despite those flaws in the game, the science behind stellar forge is actually pretty solid. Take the hot ice balls for example. Initially it's easy to write them off as bugs or just unrealism, but given 15000 atmospheres of pressure, water freezes at +250°C! As a second point, astronomers typically classify anything thats not rock, metal, helium or hydrogen as "ices." Especially things like ammonia, methane, even nitrogen. Hence the solid composition only having 3 categories: Rock, Metal, and Ice, Even for water-worlds.

So I wouldn't just dismiss the possibility of osculating orbits off-hand, however unlikely I think it may be. I suppose the easiest way to test for this is to check this system regularly and see if any orbital elements change.
