I know that I'm told that the heaviest elements can only be created in massive supernovae. Is this just theory, or have we created, in labs, lighter elements in scaled down collisions/explosions?
sigmavirus said:we're talking about HEAVIER elements, though
Lazy said:The OP did mention lighter elements as well.
Heavy elements are primarily formed through nuclear fusion processes in the cores of stars. This occurs when lighter elements, such as hydrogen and helium, undergo fusion reactions and combine to form heavier elements.
Yes, heavy elements can also be formed through neutron capture, which is the process of capturing neutrons to form heavier isotopes of an element. This can occur through various processes, such as supernova explosions or in the cores of neutron stars.
No, not all stars produce heavy elements. Only stars with enough mass and temperature, such as red giant and supergiant stars, have the necessary conditions for heavy element formation through fusion reactions.
Scientists study the spectra of stars and other cosmic objects to determine the chemical composition and abundance of elements. This, combined with theoretical models and observations from astronomical events, helps us understand the processes involved in the formation of heavy elements.
Heavy elements play a crucial role in the universe as they are the building blocks of planets, moons, and other celestial bodies. They also play a role in the evolution of stars and the chemical composition of galaxies. Additionally, heavy elements are essential for the formation of life as we know it.
