Query for those with a sense of humour who know things architect.

The obvious knee jerk reaction is "No don't do it you fool!' but my attention was drawn to this one star system with just the single (initial) build slot.
I reckon it's gonna be pretty toasty that close in - my instinct was to build a T3 station just, well just because I could, to be honest.

Would I even get the lounge bar I dream of, to sit and drink and watch the slowly expiring and expanding star swallow the station?

Should I or shouldn't I?
What (if anything) would you build?

I’d put down a scientific outpost. Pretend it’s there to study the dying star, but if this is a silly one-off…

And it’s rather likely that its expansion occurs slowly enough for a station to move outward safely as that process continues, since they should have systems in place to correct their orbital trajectory, if necessary. Until it actually has to be abandoned because of the star going boom or shedding its outer layers, but that’s likely to be so far in the future to not be a concern to whoever builds it.

(I’m also not sure if the stellar forge models such behavior for old stars anyway)

Yesterday refueled at an exactly the same system, a single Coriolis next to the Sun.
IIRC, it was Military economy with just a few products.

I've build at a K giant, it has a WW and terraformable world. Those giants don't expand much and over millions of years right? Right? Eventually they would contract(to a white dwarf iirc) too. But if it is already a giant anyway(and not into becoming a super giant or hyper giant), not much more expansion expected... right?

Click to expand...
It'll be fine... until it explodes. Or in more scientific terms, ejects its outer layers as the core, I believe, partially collapses in on itself.

Alternatively, if you're going to survive that, your planet is suddenly going to become a very effective deep freezer.

But yes, if it was not one of the more extreme main sequence stars - I'm not sure if B class goes supernova once it reaches its end of life stage again - during its prime time, you'll be off fine for at least another few million years. Give or take some. Just look at the solar masses for the better reference of what may or may not happen.

A K star does what a G star does, but slower, but whether or not it has a red giant phase depends on metallicity, some of them don't at all and proceed direct to white dwarf, because they never get onto the helium-burning runaway phase of the Main Sequence, they follow a "slightly too small and cool and not enough carbon to burn" branch instead and proceed through subgiant or go straight to white dwarf.

But there's another subtlety - because K stars are cooler the habitable zone is closer. And because the planet has to be closer it sees a much higher flux of any UV present, and some K stars are pretty bright in UV. So you may well have the liquid water oceans but they're blasted sterile, atmosphere or not.

They produce more UV when young and OP's star is only just over a billion years so if you build that station, wear sunglasses. Lenses about twenty feet thick should do...
