Habitable Zones
tkulogo:
Does anyone know how accurate the habitable zones are in Universe Sandbox²? When I calculate them manually, I get slight different result for most stars, and vastly different results for white and brown dwarfs. My system has a fresh hot white dwarf that shows a habitable zone 1000 AU across. My brown dwarfs don’t show any habitable zones, despite temperatures of over 1300K. Are these known issues? Is my math wrong?
Jar:
The habitable zones should be pretty accurate for most types of stars, though I recall there being issues with other types, for which they may be wildly inaccurate or not even show up at all. I know other users have pointed this out with brown dwarfs specifically. We should be able to do better with this with the new stellar evolution model, which is delayed a bit while work on Planet Grids.
tkulogo:
Thank you, I'll assume my math is close enough then. They're all close except for the brown dwarfs and the white dwarf that has such a vast habitable zone that it just can't be right.
Titanic:
Also, take a look at this.
Snowball earth, at the middle of the green part in the habitable zone after years and years.
Austritistanian:
I'd also like to point out about how the habitable zone isn't actually in the green part of the zone, but instead on a convergence between the green part and the red part. Any planet that are placed within the green zone would freeze below 0°C, which has been bugging me since I bought the game
