Types of Stars

5. Dwarf A small, cool star that is less luminous than the Sun, often the most common type of star in the universe.
6. System A system where two stars orbit around a common center of mass, bound together by gravity.
7. Star A star in the phase between being a main sequence star and a red giant, undergoing changes in its internal structure.
8. Binary Star A binary star system in which the brightness of at least one component varies over time.
12. Star A star whose brightness changes over time, often due to pulsations, eruptions, or interactions with a companion star.
13. Dwarf The remnant of a low to medium-mass star after it has exhausted its nuclear fuel, characterized by its small size and high density.

1. Star A collapsed core of a massive star after a supernova explosion, consisting mainly of neutrons and extremely dense.
2. Giant A large, aging star that has expanded and cooled after exhausting its core hydrogen, shining with a reddish hue.
3. Sequence Star A stable star, like our Sun, that fuses hydrogen into helium in its core, releasing energy and light.
4. A collapsing region of a molecular cloud before nuclear fusion ignites, marking the early stage of a star's formation.
6. Hole An extremely dense region in spacetime where gravity is so strong that nothing, not even light, can escape its gravitational pull.
7. Star A massive star in the later stages of its life, significantly larger and brighter than the Sun.
9. Star Two stars orbiting a common center of mass, bound together by gravity.
10. Dwarf A star, like our Sun, that is in the stable phase of its life, converting hydrogen to helium in its core through nuclear fusion.
11. Supergiant A massive and hot star with a blue-white color, found in the later stages of stellar evolution.
