When a star the size of our sun dies it will become?

When a star the size of our Sun dies, it will go through a series of stages, ultimately becoming a red giant and shedding its outer layers. This process will leave behind a dense core known as a white dwarf, which will gradually cool and fade over billions of years. The ejected outer layers will form a planetary nebula, enriching the surrounding space with elements that can contribute to the formation of new stars and planets.
