Sun-like stars cannot get us over that hump. As soon as lead absorbs a neutron, bismuth decays, and so we're back below lead again. But lead is the limit the next element upwards is bismuth, which is unstable. Strontium, zircon, tin and barium are examples smaller amounts of elements like tungsten, mercury and lead are also produced. One by one, neutrons get absorbed by a variety of nuclei, allowing us to not only create elements like nitrogen, but many of the heavier elements that go beyond what are made in supernovae.

As they evolve, however, and approach the end of their lives, these stars begin producing free neutrons, which start to get absorbed by the other nuclei present within the star. Siegelĭuring most of their lives, Sun-like stars will fuse hydrogen into helium, while during the late stages, they swell into red giants while their cores fuse helium into carbon. Wikimedia Commons users Kieff and LucasVB, annotations by E. greatest amounts of heavy elements the fastest, but the less massive ones are more numerous and are responsible for large fractions of the lower-mass elements found in nature. The next step up in mass, to Sun-like stars, makes a big difference for a large slew of elements present in our Solar System today.ĭifferent colors, masses and sizes of main-sequence stars. About 80-90% of the stars ever created are still fusing hydrogen into helium, and will remain doing so until more time than the present age of the Universe has gone by. The more numerous, less massive stars will burn through their fuel slowly, living extremely long times. During a starburst, that gas gets rapidly converted into stars of all masses and in enormous varieties of groupings: singles, binaries, trinaries, all the way up to at least sextuple systems. These events will gravitationally perturb the hydrogen gas present within a galaxy, triggering an event known as a starburst. Over the history of the Universe, the most massive periods of star formation occur when galaxies interact, merge together, or fall into massive groups and clusters. X-ray (NASA/CXC/Virginia/A.Reines et al) Radio (NRAO/AUI/NSF) Optical (NASA/STScI) This can result in severely increased rates of star-formation, similar to what we observe inside the nearby galaxy Henize 2-10, located 30 million light years away. hydrogen and helium gas present within them. When major mergers of similarly-sized galaxies occur in the Universe, they form new stars out of the.
