Our sun is a second generation star. It and our solar system coalesced from some of the remains of a first generation star that went supernova.
As I understand it, when a star goes supernova it doesn't completely "blow up". In a supernova much of the star's mass gets blasted away but some of it remains. A "cinder" is left. There are different kinds of "cinders" like black holes, nuetron stars, quasars etc. My question is that if our sun is a second generation star, where is the "cinder" from the 1st generation star that went supernova and formed all our heavey elements. I would think that "cinder" would be relatively close by(astronomically speaking). Stu |

It does not need to be nearby anymore. They have had billions of years to diverge. Also the material which formed our sun does not necessarily have to be from a single remnant.

It's not necessarily close at all. It's been 5 billion years. Things can travel a long time in 5 billion years.
Also, this is not cosmology. |
