What does the core of a star do when it blows its surface into space to form a planetary nebula?
When the core of a star blows its surface into space to form a planetary nebula, it sheds its outer layers of gas, exposing the hot, dense core of the star called a white dwarf. The white dwarf emits ultraviolet radiation that ionizes the ejected gas, causing it to glow and form the planetary nebula.
When a star has no fuel left and its outer layers escape into space what is its remaining core called?
The remaining core of a star after its outer layers escape into space is called a white dwarf. This dense core is made up of mostly carbon and oxygen and is supported by electron degeneracy pressure.
What is left when a planetary nebula dissipates?
When a planetary nebula dissipates, what remains is the core of the star that has shed its outer layers. This core, known as a white dwarf, is extremely dense and hot, gradually cooling over billions of years. The planetary nebula itself, which is the glowing gas and dust expelled by the dying star, eventually disperses into space.
Which type of nebulae formation occurs after a main sequence star casts off its outer layers?
A planetary nebula forms after a main sequence star casts off its outer layers. The ejected gas and dust create a beautiful glowing shell of ionized gas that surrounds the remaining hot core of the star, known as a white dwarf.
What is the life cycle or a sunlike star?
A sunlike star goes through the following stages in its life cycle: nebula, protostar, main sequence star, red giant, planetary nebula, and finally white dwarf. During the main sequence stage, the star fuses hydrogen into helium in its core, releasing energy. Once it exhausts its hydrogen fuel, it expands into a red giant before shedding its outer layers to form a planetary nebula. The remaining core becomes a white dwarf, cooling down over billions of years.

An average star wiill eventually becomes a?
An average star like our sun will eventually become a red giant as it exhausts its nuclear fuel. After that, it will shed its outer layers to form a planetary nebula and leave behind a dense core called a white dwarf.
What happens to the core of a star after a planetary nebula occurs?
After a planetary nebula occurs, the core of the star collapses and becomes a white dwarf. This white dwarf slowly cools down over billions of years until it eventually becomes a cold, dark remnant known as a black dwarf.
What Creates a planetary nebula?
A planetary nebula is created when a low- to medium-mass star reaches the end of its life cycle and sheds its outer layers of gas into space. This process exposes the hot core of the star, which emits ultraviolet radiation that causes the surrounding gas to glow and form a colorful nebula.
Will the sun eventually become a planetary nebula?
No, the sun will not become a planetary nebula. It is not massive enough to undergo the process that leads to the formation of a planetary nebula. Instead, the sun will eventually evolve into a red giant and then shed its outer layers to form a planetary nebula.
What do stars that have ejected a planetary nebula eventually become?
Stars that have ejected a planetary nebula eventually become white dwarfs. These are core remnants of low to medium mass stars that have exhausted their nuclear fuel. White dwarfs gradually cool down over billions of years to become black dwarfs.
After our sun becomes a Red Giant in five billion years what will it be in the next phase?
After our Sun becomes a Red Giant, it will shed its outer layers to form a planetary nebula. The remaining core will cool and shrink to become a white dwarf, gradually fading away over billions of years.
How a star becames a white dwarf?
A white dwarf is the core of a dead star. As the star runs out of fuel, it expands into a red giant, as the shell of the red giant became a planetary nebula, and the core shrinks and became a white dwarf.
