How long does it take for a massive star's core to become iron from silicon?
The process of core collapse to form iron from silicon in a massive star can occur in a matter of days to weeks. This phase, known as core-collapse supernova, is an explosive event where the iron core rapidly collapses and rebounds, leading to the synthesis of heavier elements.
How long did it take the sun to form?
3.8 to 2.5 billion years ago
Does Jupiter have an iron core?
It is believed that Jupiter has a core made primarily of rock and metal, likely composed of heavy elements such as iron and nickel. However, due to the extreme pressure and temperature conditions within Jupiter's interior, the precise composition of its core remains uncertain.
How long do Stellar Nebulas live?
Stellar nebulae, which are clouds of dust and gas where stars are formed, exist for millions to billions of years. During their lifespan, they gradually collapse under gravity to form new stars. Once the star formation process is complete, the nebula disperses or may evolve into other astronomical objects.
How does gravity effect stellar evolution?
Gravity effects stellar evolution by pulling down force on the stars while they are forming. Mass will determine how long the star stays alive and burning.

How long does it take for the core of a massive star to collapse once fusion ceases?
Once fusion ceases in a massive star, it takes only a few seconds for the core to collapse and undergo a supernova explosion.
What type of magnets are produced by running rlrctric current through a soft iron core?
Electromagnets are produced by running electric current through a soft iron core. Soft iron enhances the magnetic properties and creates a temporary magnetism as long as the current flows through the core.

What stars originated in the same stellar nursery as Sol?
We don't know. The Sun has been around for a long time, and has orbited the galactic core a number of times, while its orbit around the core has undergone many chaotic perturbations. Stars born from the same stellar nursery might be right around the corner, or they might be at the opposite side of the galaxy. Currently, we can't even tell which stellar nursery the Sun was born from, or whether it still exists.

Why is iron special in stellar evolution?
Energy is liberated through fusion reactions, producing heavier and heavier elements. There are two transient elements heavier than iron which are produced by standard stellar nucleosynthesis, but these are short lived and decay into lighter elements. Iron is the heaviest element forged in the heart of a star via standard stellar evolution. All elements heavier than iron are the byproduct of a supernova, wherein atomic nuclei are smashed together with such force energy is consumed in the nuclear reaction. This is why there tends to be an abundance of stable isotopes as light as iron, but elements heavier than iron are much more rare. Lead is an exception to this general rule as it is the end product of a long radioisotope decay sequence.
How is earths core apparently similar to some iron meteorites?
The Earth's core contains a lot of iron and nickel like a meteorite, it's why we have a magnetosphere which protects us from the sun's solar radiation (most of it)....As long as the core remains molten and in motion it'll continue to generate magnetism, otherwise we'll end up like Mars.
Will the sun become a white dwarf neutron star or a black hole?
The long-term fate of the sun according to current theories in stellar evolution, is to become a white dwarf. It lacks the mass to further collapse into a neutron star or black hole.
How can you turn a piece of iron into a magnet?
To turn a piece of iron into a temporary magnet, wind a coil of (insulated) copper wire around it and run a DC current through the wire. The iron will become the core an electromagnet -- the one you just constructed. As long as direct current flows through the coil, the iron core will attract ferromagnetic materials.jkghyjy Wrap many coils of lacquered copper wire round an iron nail. When electricity is sent through the coils, the nail becomes magnetised. The iron is an electromagnet as long as the power is on. When a piece of iron is brought near the magnet it also becomes a temporary magnet.
How long does it take iron to form?
The chemical reaction that forms the product mineral happens almost instintaneously, but for great amounts of the mineral to form depends on how much of your reactants are present, the temperature, and many other factors. Some take a few seconds and some take millions of years to form a set mass of your mineral.
