•Black Dwarf- the remains of a dead white dwarf star after its heat is
radiated into space.
•Main-Sequence Star- It is an ordinary star, one of about 90% of the stars
that can be seen from Earth. It is much smaller than a giant star. It burns
hydrogen into helium through nuclear fusion within itself. An example is
our Sun.
•Red Giant- It is a large, bright star, many times larger than the Sun, but
with a cool surface. It is believed to be in the end stage of its life cycle.
•Supergiant- It is the largest and most luminous type of star, being a dying
star. It has used up its hydrogen fuel and has begun to expand and cool.
•White Dwarf- It is a very dense, small, hot star in the last stage of its life. It
occurs when a red giant sheds its outer layers as a planetary nebula. The
electrons and protons have been packed as closely as possible by gravity.
