As in the title, are there any modern studies for how to colonize an exoplanet involving manned interstellar travel?
By this I mean an academic peer reviewed study. However, it doesn't have to be more than a theoretic paper presenting ideas.
I'm aware of Project Orion, which is by now very old. I know little (in fact, nothing) beyond that of what more modern studies might or might not exist.
If there is anything, even (one would probably rather say, obviously) purely theoretical, that proposes how to conduct interstellar travel and subsequent colonization of an exoplanet. I'd love to read it.
I'm well aware of the significant difficulties present even when theorizing colonizing the Moon, or Mars. That doesn't make this question any less serious. If there is indeed no such study, then that would be a good enough answer.
