Types of Stars

Types of Stars

Stars are huge spheres of very hot gas that emit light and other radiation

Types of Stars

This picture represents the life cycle of a star. It also represents all the different stars. As a star goes through it's life, it becomes many different types of stars

Stellar Nebula- the nebulosity surrounding a star : a star's shell or envelope of nebulosity

Massive Star- a star that has a mass eight times greater than that of the Sun

Red Giant- a very large star of high luminosity and low surface temperature

Red Supergiant- A star of 15 solar masses exhausts its hydrogen in about one- thousandth the lifetime of our sun

Average Star- a fixed luminous point in the night sky that is a large

Planetary Nebula- a ring-shaped nebula formed by an expanding shell of gas around an aging star

Supernova- the explosion of a star, possibly caused by gravitational collapse, during which the star's luminosity increases by as much as 20 magnitudes and most of the star's mass is blown away at very high velocity, sometimes leaving behind an extremely dense core

Black Hole- a theoretical massive object, formed at the beginning of the universe or by the gravitational collapse of a star exploding as a supernova, whose gravitational field is so intense that no electromagnetic radiation can escape

White Dwarf- is a stellar remnant composed mostly of electron-degenerate matter

Neutron Star- an extremely dense, compact star composed primarily of neutrons, especially the collapsed core of a supernova
