  Journey into the Heavens - A Star's Life
The HR diagram is a measure of a star's luminosity vs. surface temperature.
The reason a star is able to stay "alive" for any period of time is that the forces of the nuclear reactions in its core are powerful enough to overcome the force of gravity trying to crush the star.
For the extremely high-mass stars (greater than 15 M), even the nuclei of the iron atoms are not strong enough to resist gravity and the collapse of the core continues further.

 Star Formation, Life, and Death
Following its birth, the star enters a new phase of existance in which it leads a rather tranquil life as an inhabitant of the galaxy.
The outer layers of the star could no longer resist the central force of gravity, which was pulling the star's outer matter inward toward its core.
Alpha Orionis, commonly known as Betelgeuse is a red supergiant star marking the shoulder of the winter constellation Orion the Hunter.

 Life of a Star - Photo Composite - MSN Encarta
A star begins life as a large, relatively cool mass of gas in a nebula, such as the Orion Nebula (left).
A main sequence star (middle) shines because of the massive, fairly steady output of energy from the fusion of hydrogen nuclei to form helium.
Stars eventually use up their energy supply, ending their lives as white dwarfs, which are extremely small, dense globes, or in the case of larger stars, as spectacular explosions called supernovas.

 Star Life   (Site not responding. Last check: 2007-10-13)
Once a star is born, it spends its active life somewhere on the main sequence.
One piece of evidence for this picture is that the stellar models do a good job of predicting the existence of the main sequence and where it should be on the HR diagram.
Stars whose predicted lifetimes are less than that have left the main sequence.

 Star of Life - Wikipedia, the free encyclopedia
The Star of Life is a blue, six-pointed star with the Rod of Asclepius in the center, originally designed and governed by the U.S. National Highway Traffic Safety Administration (NHTSA) (under the United States Department of Transportation, DOT).
The Star of Life was patented by the American Medical Association (AMA) in 1967.
The Star of Life was registered as a certification mark on February 1, 1977.

 Lecture: A Star's Life
A star is in a state of hydrostatic equilibrium where gas pressure is balancing the force of gravity.
For a star to be in a state of hydrostatic equilibrium it must be very hot and dense at the center so that the force exerted by the gas can balance the crushing weight of the star's layers above the core.
The end result of all this star formation is the creation of a cluster of stars called an open cluster or galactic cluster.

The blue star of life was derived from the red Medical Identification Symbol of the American Medical Association by Leo R. Schwartz, then Chief of the EMS Branch.
The blue star of life is officially displayed on a white square background.

 Giant Star Life
Stars that are slightly more massive than the sun tend to produce energy through a different process than the PP Chain.
But in massive stars, the central temperature is higher, and this boosts the efficiency of the CNO cycle more than the PP Chain, and so it dominates over the PP Chain.
The end result of all this is for the star to become more luminous as it ages.

A star's life is determined almost exclusively by its mass.
In the picture to the right, two protons join together to form a deuterium nucleus, which is also known as "heavy water." A positron and a neutrino are released as by-products.
In a star such as the sun, this process lasts for time scales of about 10 billion years before the star begins to die.

 Star experiences life after death - Space.com - MSNBC.com   (Site not responding. Last check: 2007-10-13)
The dead star in question is Cassiopeia A, whose explosion or supernova was witnessed by Tycho Brahe in 1572.  Situated 10,000 light years away, astronomers believe a dense neutron star is all that is left of the original star.
This neutron star remnant was thought to be resting in peace, that is, until this recent discovery of a light echo in infrared images taken by NASA's Spitzer Space Telescope.
This recent activity may mean that Cassiopeia A is an exotic type of neutron star, called a magnetar.  These strange objects have surfaces that rupture and quake, letting loose tremendous amounts of high-energy gamma rays.

 A Star Is Born--Astronomy/Space lesson plan (grades 9-12)--DiscoverySchool.com
Since we cannot watch a star evolve through its entire lifetime, astronomers use their knowledge of a star’s behavior at various stages of its life to piece together a picture of the star’s entire life.
Make sure students understand that because a star’s initial mass largely determines how the star will behave at various stages of its life, observing a star at any of those stages can give astronomers information about the star’s initial mass and, therefore, about how the star was born, will evolve, and will die.
Knows how life is adapted to conditions on the Earth (e.g., force of gravity that enables the planet to retain an adequate atmosphere, intensity of radiation from the sun that allows water to cycle between liquid and vapor).
