With the collapse of the formation cloud, a hot and dense nuclei is formed, which starts to gather gas and dust. All material will be part of the star, and what's left, will form planets, moons, asteroids, or just keep as dust, spinning around the star.
Low mass stars, at the end of their lives, expel their most external layers forming a Planetary Nebula. This slowly dissipates and, in the end, will leave the stars nuclei in the middle, the so-called White Dwarf.
