The inner core of Earth is simultaneously melting and freezing due to circulation of heat in the overlying rocky mantle, according to new research from the University of Leeds, UC San ... The core of the Sun is considered to extend from the center to about 0.2 to 0.25 of solar radius (140,000–170,000 kilometres (87,000–106,000 mi)). It is the hottest part of the Sun and of the Solar System. It has a density of 150 g/cm at the center, and a temperature of 15 million kelvins (15 million degrees … Meer weergeven The Sun at the photosphere is about 73–74% by mass hydrogen, which is the same composition as the atmosphere of Jupiter, and the primordial composition of hydrogen and helium at the earliest star formation … Meer weergeven The rate of nuclear fusion depends strongly on density. Therefore, the fusion rate in the core is in a self-correcting equilibrium: a slightly higher rate of fusion would cause the core to heat up more and expand slightly against the weight of the outer layers. … Meer weergeven • Active region • Stellar core Meer weergeven Approximately 3.7×10 protons (hydrogen nuclei) , or roughly 600 million tonnes of hydrogen, are converted into helium nuclei every second releasing energy at a rate of 3.86×10 … Meer weergeven The high-energy photons (gamma rays) released in fusion reactions take indirect paths to the Sun's surface.
