Stellar husbandry

I'm not very sure I like saying that an advanced civilization MAY be able to fuse regular hydrogen through unknown means, simply because if it occurs ion stars, it SHOULD be possible to recreate. Basing it off current reactors seems just a tad silly. — Preceding unsigned comment added by 69.11.18.133 (talk) 00:07, 9 April 2012 (UTC)[reply]

Citation needed

Pretty much this entire article is "citation needed". The thermal outflow section is particularly egregious: has anybody actually done the calculation of the temperature needed to thermally eject hydrogen from a sun's gravitational well?? This is simply not possible. Geoffrey.landis (talk) 02:42, 29 August 2015 (UTC)[reply]

Merge with stellar engineering

These two articles cover overlapping ground. Geoffrey.landis (talk) 02:38, 29 August 2015 (UTC)[reply]

Calculation is wrong

“For example, lifting solar material from the surface of the Sun to the planet Mercury requires 1.6 × 10^13 J/kg” - that’s not what I get. I’m getting just 1.9*10^11, which would make it off by a factor of almost 100. And I think 1.6*10^13 is hard to believe anyway. In mks units c^2 is only 9*10^16, do you really think it takes a whole 1/5000 of its mass-energy to lift material from the surface of the sun? I don’t think many stars would even bother to be powered by fusion if you got that much out of gravitational contraction, they would heat up so much as they compress from their formation that they would resist further collapse to such an extent fusion would never happen. 71.238.109.140 (talk) 01:53, 18 October 2023 (UTC)[reply]
