The lighter the element, the faster is its average molecular speed. And those speeds for most light elements are in excess of escape velocity from small bodies. Only the gas giant planets have enough gravity to retain hydrogen, the lightest element. And as expected, those planets do contain abundant hydrogen.
So while Manuel may be right that the role of heavy elements in the Sun has been underestimated, it does not seem reasonable to me to suggest that the light elements have such a minor role -- especially if meteorites are used to suggest a standard of comparison.<hr height="1" noshade id="quote"></blockquote id="quote"></font id="quote">
You hit the nail on the head, I agree with you.
But!
<blockquote id="quote"><font size="2" face="Verdana, Arial, Helvetica" id="quote">quote:<hr height="1" noshade id="quote">The first stars are made by the extremely slow collapse of large clouds of interstellar gas under the action of self-gravitation.
Once any of the original stars explodes, the blast wave flattens the interstellar clouds, which accelerates the star-forming process and allows each cloud to form thousands to millions of stars -- one or more everywhere there is a density concentration in the flattened cloud. -|Tom|-<hr height="1" noshade id="quote"></blockquote id="quote"></font id="quote">
In my opinion
Yes, this process may aid in the rejivination of of stars, but! I cannot see it forming a gravity sink to begin with.
We know that from large compact matter such as the so called black holes eject seeds of compact matter that reforms the galaxy and seeds (gravity sinks) new stars.
More research is required in this area.
Smile and live another day
