Thanks, Stormbringer, for sharing that. Trying to overcome the hydrostatic equilibrium of a star with conventional ideas about mixing materials sounds like the most difficult way of going about stellar engineering. If we ever manage to get a space warping device to work, it might be useful for stellar engineering, as well as interstellar travel.
Imagine a space vessel with a field of contracted space in front of it, flying in through the outer layers of the Sun, and grazing the core. Fresh hydrogen would presumably be pulled into the core along with the ship. It could make repeated passes thru the Sun to deliver more and more hydrogen.
If we have learned how to make a device that can confine a hydrogen fusion reaction on Earth, this would probably provide useful lessons about how to build a space vessel that can withstand passage thru the Sun.
The article and video discuss rejuvenating a star that has apparently ceased hydrogen fusion. It would seem to make more sense to start the rejuvenation process much earlier, before the star expanded enough to harm its inhabited planets. This would be while it is still on the main sequence. Our Sun will apparently expand in this way in 500 million to 1 billion years, even tho it still has several billion more years of hydrogen fusion ahead of it.
Stellar engineering to bring fresh hydrogen into the core of a star would apparently have the effect of reducing the intensity of the the fusion process, and so the luminosity of the star. The star would appear anomalously dim for its age, as determined by other methods. This is just what we seem to find in the stars Zeta 1 and Zeta 2 Reticuli.

Great thread S&F!
I'd like to add that maybe a binary star system might encourage space flight a lot differently compared to our star system.
If we had a more exotic and intriguing solar system do you think we would be more inclined to explore?
Awesome astrophotography JadeStar. Where can one get the Planetary Habitability Simulator from? That looks like a fun piece of kit to have on hand.

It's too bad NASA cancelled the Terrestrial Planet Finder (TPF) due to funding. I've been looking for recent news on Zeta Reticuli, but can't find any. Anyone have any updates?
