The hypergiant is a yellow hypergiant (YHG) which is currently cooling down and becoming a red hypergiant. It is roughly something that has a spectral type of maybe G3 0-Ia, though the exact spectral type doesn't matter. I chose a yellow hypergiant because they are rare and slightly unstable and undergo changes in their apparent magnitudes.
The Star System
The star system consists of a K2V star and I would like the star system not to be disrupted. Its outer influence is probably something like ≈50,000AU but this is a rough estimate.
- Mass - 0.82 M☉
- Luminosity - 0.452 L☉
- Radius - 0.853 R☉
- Habitable Planet Distance from star - 0.66 AU
- End of My Star's Oort Cloud - ≈50,000 AU but this is a very rough estimate
Is it possible for the hypergiant to be extremely bright while not affecting the star system (so it can be important for the people in the habitable planet's mythology) and where approximately would the hypergiant have to be?
Note: I can give you more info. Just ask.
