Making Suns
Why Worldbuilding Stack Exchange recommends it
Worldbuilding Stack Exchange answerers point people to it when a setting needs artificial or tunable stars, and for ideas on packing or engineering stars in tight spaces.

What it is
An Isaac Arthur Science & Futurism episode on whether civilizations could build artificial stars, from mimicking natural suns to creating exotic types nature does not produce. It is a narrated, speculative engineering overview of star-making and the options it opens for colonizing space.

I just watched this awesome video, and at the end Isaac talks about this roughly, although the scale is way larger [this video]

Have you considered artificial stars? There are several ways to crate an artifical star whose parameters you can tweak with great precision. The YouTube channel SFIA [LINK] made a video on Making Suns [this video] a while back. While these solutions require some really extreme engeneering, they get you around gravitational, thermal and tidal issues. From sane to wacky my suggestions are fusion planet, penrose, stellar flashlight, penrose star and a kugelblitz. Let's take a look at each of them fusion planet Build a planet of deuterium and helium-3 under 13 jupiter-masses (to prevent deuterium fusing with itself). Use orbital rings [LINK] to build a mega-earth [LINK] around it, place fusion reacto

And following from my other comment, Isaac actually made another video with a similar premise towards the end; you could pack quite a few red dwarfs/mini-systems into a span of 1-2 light years if you really wanted. One possibility would be to basically stripmine the galaxy and create a bunch of red dwarfs with dyson swarms around them in a relatively small space. Same result as before, but more grandiose.
