Iron's quantum role in planet formation.

    Iron's quantum role in planet formation. 

ScitechDaily mentions iron's quantum role in planet formation like this: "The evolution of our planet may be largely driven by the microscopic quantum state of iron atoms. Iron’s “spin state,” a quantum property of its electrons, affects its magnetic behavior and chemical reactivity. Variations in the spin state can impact whether iron is found in molten or solid form and its electrical conductivity".

Ferromagnetism is one of the reasons why iron plays a big role in planet formation. Small-size iron bites can go together. And that makes them create the static core, a gravitational center that pulls other particles and objects into it. Iron can turn magnetic in the interplanetary magnetic field. And also the poles that form magnetic powerlines in the galaxy can create ferromagnetic phenomena in iron. 

In some models, very thin wave movement that travels through iron atoms transports energy away from iron. That wave movement acts like a thermal pump that transports energy out from iron in one direction. That thing makes a phenomenon called ferromagnetism. In very cold conditions in space, iron can turn very easily to ferromagnetic. 

The hydrogen halo around the galaxy tells that things like Sagittarius A have poles. That causes interesting visions about the interplanetary nebulas, that could involve lots of iron. It's possible that iron in those nebulas can turn magnetic, and then there could be a dominating gravitational center in the molecular nebula. 

Planet formation in nebulas around young stars is interesting. Star must collect molecular nebula around it. There must be solid and heavy elements in that nebula that rocky planets can form. Iron in those nebulas formed in stars that blasted a long time ago. 

"Deep inside rocky planets like Earth, the behavior of iron can greatly affect the properties of molten rock materials: properties that influenced how Earth formed and evolved. Scientists used powerful lasers and ultrafast X-rays to recreate the extreme conditions in these molten rock materials, called silicate melts, and measure properties of iron.

When protoplanet formation begins the star's fusion must not begin in the wrong moment. If the fusion reaction starts before the protoplanet's mass turns high enough. That radiation from fusion in the star will not destroy those protoplanets. When fusion starts. It just pushes particles to a longer distance. 

If the distance between a star and its protoplanets is too long. Those protoplanets will turn into gas giants like Uranus. The weak solar wind will not blow gas from around those planets. And the result is gas giants or if those protoplanets are close enough they can impact together and form brown dwarfs. If a protoplanet is too close to its sun, solar wind or particle flow from that star pushes the atmosphere off the planet. If the protoplanet is not large enough that particle flow can completely push that dust away. 

The dust that forms planets requires a core that can anchor other elements around it. Without that nucleus. The dust will travel away when the solar wind blows it. 

Iron is one of the lowest energy and the most stable elements, in the Universe. In this model, iron pulls other particles into it because energy travels from higher energy particles to lower energy particles. And that means iron starts to collect other particles around it. Ferromagnetic objects also pull things like ions into them. So iron has a big quantum role in planet formation. Iron is the heaviest element that forms in a normal star's nuclear reactions. And that thing causes the effect, that iron can act as a core where other elements are connected. 

So deep inside Earth iron makes a static core. And that thing allows iron to collect other elements around it. Things like ferromagnetism make it possible for iron can form a static gravitational center, even if there are no large iron bites all around in the forming planetary system or gas nebula around young stars. 

Things like kilonovas can make heavier isotopes and elements than iron. But those things are quite rare, and heavier elements can form inside super giant stars. But the formation of those heavier elements like Uranium happens just in the last moments of those giant stars when they detonate as supernovas.
