But if it were a few per cent stronger, the temperature of the solar core would have been boosted so much the sun would have burned out in less than a billion years — not enough time for... (newscientist.com)
Physicists and astronomers believe that the Sun shines because of the conversion of hydrogen nuclei (protons) to helium nuclei (alpha particles) in the solar core (see Figure 1a). (newscientist.com)
If true, it would mean there is a connection between the physics of the solar core and the solar wind, even though the core is denser by 24 orders of magnitude. (newscientist.com)
