A query about the formation of our sun...?

Question

Do astrophysicists believe that the sun formed from the recombination of material from a very massive first generation star that may have exploded or from a combination of remnant material from maybe more than one very massive first generation star that amalgamated within a spiral arm of our galaxy? Since bing bang theory can only account for elements up to Li-7, the fact our planet has natural elements up to the atomic number of 92 shows that they could only have been fusion products cooked inside of an earlier star. If the universe is almost 14 billions years old and our sun is 4.6 billion years old, these ancient stars had to burn out very, very quickly to have been able to reasseble into our sun. Does the time required even rule this out and that maybe the material was helped along to formation by another blast wave or interaction with some large object like another star?

Answer 1

I think suns form from an explosion happening when the condesation of a black hole reaches the critical point where no more mass can be added - the intense gravity involved with black holes keeps the explosion from making the suddenly burning matter disappear into the nether of space.

That same gravity induces the new sun to become the center of its own system drawing in and keeping in rotating orbits matter that would have passed or also been eaten by the black hole.

Answer 2

usually when stars form they start out as a GMC or giant molecular cloud. and something like a supernova or other distortion in gravity kicks off this process of star formation. now the fact that our planet has so many elements is becaue of supernovas. a star can make any element up to iron and then stops there, but when a sufficiently large star implodes it produces enough energy to fuse larger nuclei into more complex atoms. Now im not sure but i think the sun is a third generation star. The more ancient stars are thought to have been very large, and the larger the star the shorter the lifespan. hope this helps

Answer 3

Massive type O stars last no more than a few million years, so it didn't take long for heavier elements to form. It is thought that some external nudge - a supernova shock wave, or a density wave in a spiral galaxy - is what most often initiates star formation.

Answer 4

It's generally believed that the shock front of a relatively nearby supernova compacted regions within an existing nebula, and that from that compacted area our sun and planets gradually accumulated.
