When the layers escape into space, this is classified as a planetary nebula. What usually is left behind is a white dwarf.
A White Dwarf Star remains.
You take a left at the nebula
When smaller stars explode (like our Sun), they leave a nebula cloud by releasing their gas and they become a small but dense white dwarf star.When big stars explode (like Betelgeuse), they have a massive explosion called a supernova and the core of the star turns into a black hole or a pulsar.
The sun is in its middle age. Its around 5 billion years old, and will keep fusing hydrogen into helium for another 5 billion years. In about 5 billion years the sun's core will run out of Hydrogen and begin fusing helium into carbon. At this point the sun will balloon outwards become 1 to 10 times its current size but the surface temperature will lower because it is further from the core. It will turn red in color and eventually after it has fused all the helium into carbon it will release its out layers into what is known as a planetary nebula and nothing will be left but the white hot core known as a white dwarf star.

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.

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.
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
There is not chance the Sun will become a black hole. It does not have enough mass to achieve this, nor does it have any chance of gaining any. Our Sun will die in about 5 billion years time, first as a red giant and then after it has created a planetary nebula, all that will be left, will be a white dwarf.
When large magnetomotive force is applied to the core and then removed. The flux in the core doesn't reach zero. Instead, a magnetic field is left behind in the core. This magnetic field is called residual flux in the core. MOHSIN BB-EE-NED
A disc-shaped cloud of gas and dust left over from the formation of the Sun.
A Nebula is a massive cloud of dust, gas and debris (sometimes left over from a star that has died in a supernova explosion) drifting in interstellar space. It is from these nebula that stars are thought to form. Once the stars "come to life" this is thought to kick start the formation of other stars and planets from the remaining gas, dust, rock, metal in the dust cloud.
