The remnant star left at the core of a planetary nebula is called a white dwarf. After a star like the Sun exhausts its nuclear fuel, it expels its outer layers, forming a planetary nebula, while the hot core remains as a white dwarf. This stellar remnant is primarily composed of carbon and oxygen and gradually cools and dims over time.
What else can I help you with?
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.
When a star has no fuel left and its outer layers escape into space what is its remaining core called?
When the layers escape into space, this is classified as a planetary nebula. What usually is left behind is a white dwarf.
What is a plantary nebual?
A planetary nebula is a glowing shell of gas and dust formed by a star shedding its outer layers at the end of its life. Despite its name, it has nothing to do with planets. The glowing gas is illuminated by the hot core of the star left behind, known as a white dwarf.
9 stages of a star?
Stellar nebula: a cloud of gas and dust in space. Protostar: a young star still forming through gravitational collapse. Main-sequence star: stable fusion of hydrogen into helium in the star's core. Red giant: expansion of the star as it runs out of hydrogen fuel. Helium fusion: fusion of helium atoms in the core. Planetary nebula: outer layers of the star expelled into space. White dwarf: the core left behind after the outer layers are ejected. Black dwarf: a cooled and dim white dwarf. Supernova or black hole: the final stage, depending on the mass of the star.
What is the deinition of Nebula?
a nebula is the cloud of radioactive material dust smoke and debris caused by an exploding start, a nebula happens after a nova or super nova..and somtimes the collapse of a start causes black holes too in which case you wont see a nebula because the massive amount of gravity in the black holes sucks everything in, but yes a nebula is the cloud left over from an exploding star

What is a star left at the core of a planetary nebula?
A star left at the core of a planetary nebula is typically a white dwarf, which is the remnant of a low to medium-mass star that has exhausted its nuclear fuel. After shedding its outer layers and creating the nebula, the core remains hot and dense, gradually cooling over time. White dwarfs no longer undergo fusion reactions and will eventually fade away, leaving behind a cold, dark remnant known as a black dwarf, although the universe is not old enough for any black dwarfs to exist yet.

What will the Sun become when it has used up all its energy?
The Sun will eventually evolve into a red giant as it runs out of hydrogen fuel in its core and starts burning helium. After that, it will shed its outer layers to form a planetary nebula and leave behind a hot core called a white dwarf.

Stages of star life in order?
1. Birth 2. Main sequence star phase 3. Deplation of hydrogen and helium fuel and expansion phase 4. Dying phase : either simple ejection of outer layers or explosion as a nova 5. Last phase : Black hole, neutron star or white dwarf
There is enough fuel remaining in the sun to last for another?
Roughly 5 billion years. It will expand into a red giant followed by throwing off its outer layers forming a planetary nebula. The only thing left over will be the extremely hot core that will cool into a white dwarf over billions of years.
What is the process by which an originally homogeneous Earth developed a dense core and a light crust?
The process by which Earth developed a dense core and a light crust is called planetary differentiation. During the early stages of Earth's formation, heavy elements sank towards the center due to their higher density, forming the core. Lighter elements were left to accumulate near the surface, forming the crust. This process was driven by the heat generated from the collision and accretion of planetesimals during the early solar system formation.
How does a planetary nebula form?
A planetary nebula is created when a star blows off its outer layers after it has run out of fuel to burn. These outer layers of gas expand into space, forming a nebula, which is often the shape of a ring or bubble. About 200 years ago, William Herschel called these spherical clouds planetary nebulae because they were round like the planets. At the center of a planetary nebula, the glowing, leftover central part of the star from which it came, can usually still be seen.A planetary nebula is a cloud consisting of the outer layers of gas which have been ejected after the death of a star about the mass of the Sun.
Core plugs are also called?
Core plugs are also known as freeze plugs or expansion plugs. They are used to seal the holes left in an engine block after the casting process.
