At what Tech Level would a solar rejuvenator be a reality?

[Twin Agate Dragons]

If scientists found out that star was about to go nova or supernova and that threatened the planet the resided on and they had enough time to build a solar rejuvenator to prevent the star from going [super] nova, at what Tech Level would such a technology be feasible?

Clarkian (as in "sufficiently advanced"/"indistinguishable from magic"). Stars, especially stars that are likely candidates for going nova, are BIG. The smallest of them would give most jovian and superjovian planets serious inferiority complexes.

I think it might BARELY have been within the capability of Yaskoydray, but I've never seen any meaningful definition of what TL he was at.

A star about to go supernova is already a supergiant - the only way to stop it would be to either change physics so that iron can be fused inside stars, or inject more heavy elements below iron in the fusion chain around the core so it would have more of that stuff to fuse, essentially delaying the explosion. Both of those are pretty much impossible, though the latter is less so .

As for novas... white dwarfs go nova by accreting and igniting material from stars that they orbit. If you had a way to change the orbit of the white dwarf so that it didn't pull material off its companion star anymore then you'd be able to prevent it from going nova. That's more doable with SF tech - you could either do it with some kind of gravitic focussing or even by swinging a lot of asteroids past the WD in the right way so that they expand its orbit over time (like, a timescale of thousands of years at least).

Hmmm...

2 ideas

1. In Classic there were devices that manipulated the value of the strong nuclear force (nuclear damper fields etc). Build a huge one and then you might be able to do something with the star's fusion reactions before it reaches supernova stage.

2. Use Grandfather tech to pinch off the star into a pocket universe before it goes supernova

Depends what you want to achieve really

My question is "why would you even need to know?" It is not likely for the Traveller game that a PC or NPC would ever get some type of tech anyway. So why care or even have it in the game?

Supernovae are somewhat game-changing. For example, if Antares blows, then pretty much all the habitable worlds in the sectors around it will be rendered uninhabitable because of the radiation when it gets there (you have to be several hundred lightyears away to be reasonably safe). You'd need massive evacuations away from the danger zone, at least out to where the radiation is only an inconvenience and not actually deadly.

That said, you can't really stop them, so they're more a force of nature/'act of god' type thing.
