Why the sun didn't absorb heavy elements from early solar system?

Click For Summary

Discussion Overview

The discussion revolves around the formation of the solar system, specifically addressing why the sun did not absorb heavy elements from the early solar system, and instead, these elements remained around the sun to form planets.

Discussion Character

  • Exploratory
  • Conceptual clarification
  • Debate/contested

Main Points Raised

  • One participant questions why heavy elements did not get absorbed by the sun during the solar system's formation.
  • Another participant suggests that the sun does not absorb planets, implying a similar reason for the lack of absorption of heavy elements.
  • A humorous remark is made about "virtual gnomes" preventing absorption, indicating uncertainty about the mechanisms involved.
  • It is noted that there are heavy elements in the sun, and the inner planets lost lighter elements like hydrogen and helium due to their inability to retain them.
  • A participant inquires about the location of heavy elements within the sun, leading to a response that heavy elements are distributed throughout the sun and have settled over time.
  • Another participant asserts that the sun contains more heavy elements than all the planets combined.

Areas of Agreement / Disagreement

Participants express varying degrees of understanding and uncertainty regarding the mechanisms of heavy element retention and absorption by the sun, with no consensus reached on the specific reasons for the observed phenomena.

Contextual Notes

Some claims about the distribution of heavy elements in the sun and the dynamics of the solar system's formation remain unresolved, with assumptions about the processes involved not fully articulated.

Hi,

ive been studying formation of solar system and couldn't find an
explanation for why the sun didn't absorb heavy elements from
early solar system? why they remained around the sun and formed
planets and not get absorbed to the centre?

thanks in advance

Probably for the same reason the sun does not "absorb" the planets!

I dunno... Virtual gnomes don't allow it?

They're too 'heavy'? That's at least part of it, right? Inknowledge me!

There are heavy elements in the sun. The four inner planets lost most of their hydrogen and helium because these elements were too light to hold onto.

thanks, that seems correct, but where do these heavy elements reside in the sun?

There are heavy elements throughout the Sun. The photosphere now has about 16% less heavy elements than it did 4 billion years ago, as the heavy elements have settled slightly.

The gas and dust that formed the solar system had various elements throughout the cloud. During collapse the elements near the center were pulled in and formed the Sun, while the little that remained out of the Sun formed the planets, asteroids, and other small bodies.
 
thank you for your complete answer, that cleared my confusion completely

There are plenty of heavy elements in the sun. It's probably more than on all the planets combined.
