WebThe sun generates its energy through nuclear fusion, making helium from hydrogen. The main process by which this happens, called the protonproton chain, goes as follows: - Two protons come together to create deuterium, a positron, a neutrino, and energy: p + p? D + e + + v + energy - The deuterium fuses with another proton to make 3 He: D + p? 3 He + … http://scihi.org/pierre-janssen-discovery-helium/

WebHelium-3 boils at 3.19 K compared with helium-4 at 4.23 K, and its critical point is also lower at 3.35 K, compared with helium-4 at 5.2 K. Helium-3 has less than half the density of helium-4 when it is at its boiling point: 59 g/L compared to 125 g/L of helium-4 at a pressure of one atmosphere. WebOn the helium main sequence, the Sun's luminosity will hold at about 45 L o before brightening to about 110 L o at the end. Not so impressive as a red giant, but very bright nonetheless. To maintain its subgiant lifestyle the Sun must tear through the fuel in its helium core 100 times faster than it did with its original hydrogen core.
