It's basically a run-away effect, once the sun starts fusing helium into carbon the core temperature rises extremely fast and within a few minutes of the helium core being sufficient in mass/temp/density the entire core (40% of the solar mass) is converted to carbon. The only thing that allows a star to cool besides radiation is hydrostatic equilibrium, adding heat without that mechanic is just that - adding heat. Adding heat to our sun right now wouldn't do much, the core would proportionally expand and cool for the given amount of heat. However, unlike the younger sun, the great deal of heat this adds doesn't cause the electron-degenerate helium to expand and cool.

Eventually, when the helium core is sufficiently massive, dense, and hot, it will ignite and burn within a matter of minutes When gravity compresses the core enough that it's temperature reaches 100M* K it begins the Triple Alpha Process, fusing helium into carbon. Image Copyrights: Prabhu AstrophotographyДЇor those of you that don't know, the colors are actually the star expelling its own matter in sort of shockwaves as it 'collapses' on itself, as gravity wins the everlasting struggle against the star.ДЄ star is able to last through it's entire main sequence via the pressure that nuclear fusion is applying against gravity, but as the hydrogen becomes less and less (as it's fused into helium) and helium 'ash' begins to pile up at the center, gravity crushes the core even further, making much of the helium ash electron-degenerate - making it denser, hotter, and applying higher pressure at the core.

The remnant central stellar core, known as the central star (CS) of the planetary nebula, is destined to become a white dwarf star. Gases from the star in the surrounding space appear, from our vantage point, as if we are looking down a helix structure. The Helix Nebula is an example of a planetary nebula, formed by an intermediate to low-mass star, which sheds its outer layers near the end of its evolution. The Helix Nebula has sometimes been referred to as the 'Eye of God' in pop culture. The Helix Nebula is a planetary nebula (PN) located in the constellation Aquarius, it is one of the closest to the Earth of all the bright planetary nebulae at 655 light-years away.

Simbad bibliographic survey began in 1850 for stars (at least bright stars) and in 1983 for all other objects (outside the solar system).
