Questions about the Sun

No. There may be lots of iron spread out in certain layers of the sun but not the inner core. The inner core will be the most extreme part of the sun due to the immense heat and pressure , thus most likely to be composed of plasma and no solid matter.

I'm not saying a solid iron core.

Massive stars have Iron at it's centre but despite the fact that the sun cannot fuse heavier elements Iron is littered through our solar system and should've been accreted by the sun during it's formation. I can get the notion that the sun doesn't produce the same layers as massive stars when the convection is strong enough but surely there should still be a material ratio over it's diameter.

The sun does not have iron (solid or liquid) in its core, the temperature and pressure is just to great for heavy elements to exist. Stars start to produce heavier elements such as iron once their hydrogen and helium fuel source runs out and they start using heavier elements like carbon, nitrogen and oxygen as fuel for fusion . Our sun is far from that stage in human years

But this is why I’m arguing. You’re trying to say the temperature and pressure of a mediocre star is greater than that of a star which succeeds in fusing stuff like silicon and oxygen?

What is a "mediocre" star? White, red, blue, yellow? I think you're confusing yourself because I never compared temperatures of any star. I've only been referring to our sun

Mediocre is a common white main sequence star. Massive stars such as in the early universe are blue bright. Their fusion cycle looks like this:

Core-collapse | COSMOS

astronomy.swin.edu.au astronomy.swin.edu.au

The heat and pressure to create iron is much greater than what you’re saying is prohibiting the existence of iron at its center. Our star is the remnant of old stars, just like the rest of our solar system it contains all the material just a lot more hydrogen.

I can still see the convection being strong enough to prohibit iron condensing right at it’s centre. But you’re argument contradicts the physical functional parts of massive stars.

Is our sun collapsing? Has it run out of Hydrogen and Helium? Back to your original question of does the sun have an Iron Inner Core. Still no I do not think it does not.

No for the 4th time. The sun isn’t fusing any silicon into iron. But the sun is made out of the same stuff the rest of the solar system is made of.

So I’m searching for a reason why it shouldn’t have a inner iron core.

At 0.14% it's entire mass being iron that's around 46000 the mass of the earth worth of iron. Why does a super hot star like a blue giant have heavier materials sink to the centre but not the sun?

I have been saying it for the past 3 replies and the answer is also in link you had. The sun still has lots of hydrogen left to use as fusion fuel for the creation of helium.

My god man. :ROFL: Read please.

Why does our planets have iron cores? We're not fusing anything..?

I give up. Feel like you're pulling my leg at this point.

I'm really not. I just don't think you understand what I mean when saying the sun accumulated heavier elements during it's formation vs the sun makes iron at its core.

Look at the composition of the sun again please:

0.14% Iron that's 46000 the mass of the earth in iron. What is the limiting process stopping this to accumulate at the centre since it's heavier in density than basically everything else?

Convection and turbulence.

I think this is the most credible answer but... How should this apply to the sun which isn't nearly as hot or energetic as massive stars. These seems to have no problem accumulating Iron towards its centre? And those stars even fuse silicon to become endothermic by nature. The temperatures are orders of magnitude greater than our sun.

Iron boils at about 3000 degrees C
Sun's internal temperature is several million degrees C

How do you think solid metal iron is going to form? It's all plasma and mixing around like crazy.

Where did I say there's could be a solid iron core?

Have you look at the the layers of more massive stars despite it all being mixing plasma?

Nope
Can't get close enough.
