How could a rocky planet be tilted on its side?
If you're willing to wait hundreds of millions of years tidal forces can do it. Over the last 500 million years, the moon has changed the earth's rotation 10% (from a 22 hour day to a 24 hour day).
We …

How could we (modern humans) get established on a hot planet?
You cant land. No I mean its physically impossible to.
I dont know the exact proportions of the various gases you listed, but assuming co2 is the most common, at that temperature and pressure it's abo …

A Habitable Zone Within a Habitable Zone--Would that Make any Difference?
be ignored:
Or when the suns are weak, and the planet's atmosphere is thick and an extreme insulator that can hold heat for a full year (think venus here), you can theoretically have nested rings of habitability … zones depending on the temperature gradient:
However none of these special cases probably apply to your system, your habitability zone probably can't be described using radii alone. …

Living on a planet years before a supernova
I'm assuming no-one would be silly enough to start a settlement in the neon, oxygen, or silicon stage of star evolution - we would do a proper habitability check including analysing the sun. … The system would've been stable for about 2000 years at this point, and there'd be an established habitability zone. …
