Supernova Remnants: the Formation of the Earth?

[deepnessdawn]

The nuclear fusion inside the sun asmain-sequence star only produces helium now. But, there are heavy elements, evenincluding iron, found in solar spectrum. And the earth contains various heavyelements. Where are these heavy elements come from?

 

 

 

Reference viewpoint:

 

The formation of the earth probably camefrom heavy elements condensate of the supernova ejecta of last generation starin the inner orbit of solar system. The age of the earth is 4.6 billion years.Now the sun is a main sequence star, and experienced approximately 4.57 billionyears. There are various heavy elements, including iron, found on the surfacegas of the sun, while the first generation main sequence stars almost only contain hydrogen and the production of light nuclear fusion——helium.

You appear to ask and answer your question in this post: heavy elements come from supernovae. Was there some other point?

It's not that earth has a lot of iron, but that most the hydrogen gas couldn't "stick". The result in 4.5 billion years is an iron core with little atmosphere.

Interesting way to ask a question. Have you ever thought of proof reading your post and inserting spaces between words and sentences? David Levy also has that tendency to omit spaces between words. Are you David? Anyhow, I appreciate your enthusiasm for astronomy. Yes, the heavy elements are created when massive stars supernova, and the Earth formed from the remnants of supernovas. What is your question?
