| Mar 14, 2017 at 19:03 | comment | added | ProfRob | @Zhe (cc Aaron Franke) You have perpetuated the myth that elements beyond iron are not formed during a star's "normal lifecycle". Ever since the detection of short-lived Technetium in the atmospheres of some giant stars in the1950s we have known otherwise. They do not form by fusion, but by neutron capture. | |
| Mar 14, 2017 at 2:22 | comment | added | userLTK | @AaronFranke You're right about that, though those elements spread across the galaxy and became part of new solar system formation from the supernova explosion. My bad. | |
| Mar 14, 2017 at 1:53 | comment | added | Aaron Franke | @userLTK You're wrong about the first part. Oxygen, Silicon, Iron, are all formed during a star's normal lifecycle, not a supernova. Any element iron or below can be formed during a star's normal lifecycle. A supernova causes the formation of any element Uranium or below (so basically all of them). | |
| Mar 14, 2017 at 0:24 | comment | added | userLTK | This might get you started: space.com/16943-supernova-explosion-solar-system-formation.html Elements like Oxygen, Silicon, Iron are all formed in a supernova. As I understand it, chemistry happens too, on a limited scale, within the nebula, so you have basic building blocks. Silicates like SO2, Ices/gases like H20 and CO2, but I'll let someone smarter than me give a more complete answer. Solarsystems don't form out of hydrogen easily because it's too light, it takes a certain amount of heavier elements. | |
