Webb14 feb. 2024 · A star lives while there’s balance between the outward push of energy from nuclear fusion and the inward press of gravity. A star dies when it runs out of fuel and the balancing act ends. Read more: Webb15 dec. 2006 · A lmost all elements heavier than helium are produced in stars. Nuclear fusion reactions can produce elements up through iron, but most heavier elements result from a series of neutron absorption reactions (interspersed with radioactive decays of unstable neutron-rich isotopes).
