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.
they become a nebula
They explode as a supernova/hypernova to form a planetary nebula/black hole.
The next stage in the life of the sun is the red giant phase, where it will expand and become much larger. Eventually, the sun will shed its outer layers and form a planetary nebula, leaving behind a remnant core known as a white dwarf.
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.
A planetary nebula consists of gas ejected from old red giant stars.

Typically it is called a planetary nebula. It has nothing to do with planets.

Star of one stellar mass, red giant, white dwarf, planetary nebula
Star of one stellar mass, red giant, white dwarf, planetary nebula
A star's life cycle starts from a nebula. For giant stars, the star turns into a huge star to a super red giant to a supernova to a black hole. A sun-like star turns to a red giant, then a planetary nebula, a white dwarf, and then a black dwarf.
It will become a Red Giant and then it will slowly fade away into a new nebula.
