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.
A remnant of a red giant is called a planetary nebula or a white dwarf, depending on the mass of the original star. When a red giant exhausts its nuclear fuel, it sheds its outer layers, creating a colorful shell of gas known as a planetary nebula. The core that remains can become a white dwarf, which is a hot, dense stellar remnant that gradually cools over time.
they become a nebula
They explode as a supernova/hypernova to form a planetary nebula/black hole.
When a red giant expels about half of its mass into space, it forms a planetary nebula. This nebula consists of the outer layers of gas and dust ejected from the star, while the core that remains becomes a white dwarf. The planetary nebula glows due to the ultraviolet radiation from the hot core, illuminating the expelled material. Over time, the nebula disperses, enriching the surrounding interstellar medium with heavy elements.
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.

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.
