Giant star
A Giant star is a star that has stopped fusing hydrogen in its core. More specifically, the term giant star refers to a star that belongs to the luminosity class III in the Yerkes spectral classification.

A dark scar floats during the extreme southern hemisphere of Jupiter in this Hubble Space Telescope image. The scar appeared in July 2009, the likely result of a rocky asteroid ramming into the giant planet.

Giant Star Life
Overview
A star's life is determined almost exclusively by its mass. Large stars (above about three solar masses) live much shorter and violent lives than most other, average-sized stars (such as our sun).

Galileo Finds Giant Iron Core in Jupiter's Moon Io
Jupiter's volcano-pocked moon Io has been found by NASA's Galileo spacecraft to have a giant iron core that takes up half its diameter, scientists report in today's issue of Science magazine.
Neptune, gas giant with great dark spot
Neptune, is the fourth largest of the planets in the solar system, and eighth major planet in order of increasing distance from the Sun. It is similar in size and structure to its neighbour Uranus.
Yes, there are many types of giant stars, blue-white, white, yellow, orange, and red. Yellow giants are a phase of stars with masses heavier than the sun, but it is phase that doesn't last very long, so there aren't many of them.

GIANTS AND DWARFS
Let's consider some examples to clarify these ideas. The star known as Mira (Omicron Ceti) has a surface temperature of about 3000 K and a luminosity of 1.6 1029 W.

Giant
1. A star that has evolved off the main sequence and is roughly a hundred times as luminous as the Sun. Giants can be of any color, but yellow, orange, and red giants are the most common. 2. A planet much more massive than Earth.
Giant stars. Stars that are swelling in size as they approach the end of their lives. Giant stars are often no more massive than the Sun but they have expanded to great size and are therefore less dense but highly luminous.

red giant
A relatively cool star which is near the end of its life, swelling in size after the inner core has been depleted of hydrogen.
RED GIANT STAR
A red giant is a relatively old star whose diameter has swollen enormously. It's temperature has also cooled appreciably, it's contracting hydrogen core has turned to helium and eventually to carbon.
Red Giants
Finally we get to the red giant stage; I know you have been waiting for this for some time, so just try to stay calm.
This giant planet has no solid surface. Under its atmosphere is a large liquid ocean of hydrogen and water. What lies in between that ocean and the atmosphere? Actually there is no in between.
Supergiant: Very luminous star 10-1000 time more massive than the Sun.
Superluminal velocity: The apparent motion of an object at greater than light speed; This appearance is caused by a "projection effect" by the object's motion toward Earth.

THE DEATH OF STARS
Stars expand as they grow old. As their core runs out of hydrogen and then helium, the core contacts and the outer layers expand, cool, and become less bright.
Giant ellipticals are probably formed by mergers on a grander scale. The Milky Way and M31 are gravitationally bound, and currently approaching each other at high speed.
Giant jets of superfast particles are powered by supermassive black holes at the cores of galaxies. Both elliptical and spiral galaxies harbor such black holes, but only Speca and one other spiral galaxy have been seen to produce large jets.

Giant Molecular Cloud: A region of dense interstellar medium that is sufficiently cold that molecules can form. They are very cold (10-20K) with relatively high densities (trillion particles per cubic meter), and huge.
Red giants can have strong ``winds'' that dispel more mass than all of the stellar winds that occurred during the long main sequence stage.
Red giant or supergiant stars with degenerate neutron cores, often abbreviated TZO's. If they exist, such objects would be nearly impossible to identify observationally.

Red giants form from the remains of most stars, at least for a while, and are a remarkable machine in the clockwork of the universe. Our Sun has been shining now for, it is estimated, some 5 billion years.
The giant star is about 7.4 times the diameter of the sun. The dynamics of the orbit indicates that the giant has a mass of 10.9 solar masses, while the smaller star is about 6.8 times the mass of the sun.
