 Star - Wikipedia, the free encyclopedia   (Site not responding. Last check: 2007-11-06)
Stellar astronomy is the study of stars and the phenomena exhibited by the various forms/developmental stages of stars.
As learned by star formation astronomers, stars are born in molecular clouds, large regions of slightly higher density of matter (though still less dense than the inside of an earthly vacuum chamber), and form by gravitational instability inside those clouds triggered by shockwaves from supernovae.
Most of the matter in a star is blown away in the explosion (forming nebulae such as the Crab Nebula) but what remains will collapse into a neutron star (a pulsar or X-ray burster) or, in the case of the largest stars, a fl hole.

 Star - Wikipedia, the free encyclopedia
A star is a massive body of plasma in outer space which is currently or has in the past produced energy through nuclear fusion.
All stars except the Sun appear to the human eye as shining points in the nighttime sky that twinkle because of the effect of the Earth's atmosphere.
The smallest known star undergoing nuclear fusion in its core is AB Doradus C, a companion to AB Doradus A, which has a mass only 93 times that of Jupiter.

 List of brightest stars - Wikipedia, the free encyclopedia
Below is a list of the most luminous stars by absolute magnitude.
The absolute magnitude is a measure of the star's luminosity – the total amount of visible energy radiated by a star every second, as it would be at a standard distance of 10 parsecs away from the star itself).
Note that even the brightest star, at a luminosity of 40 million suns, it is still not the brightest object in the universe.

 World Almanac for Kids
The largest stars known are supergiants with diameters that are more than 400 times that of the sun, whereas the small stars known as white dwarfs have diameters that may be only 0.01 times that of the sun.
The birth of stars is intimately connected with the presence of dust grains and molecules, as in the Orion nebula region of earth’s galaxy.
Stars are generally born in small groups at one edge of a large molecular cloud.

The star is a companion to a Sun-like star toward the center of our Milky Way Galaxy.
It was found and measured by observing changes in the light output of the system when the smaller star passes in front of the larger star from our vantagepoint.
The star is more than 50 times as dense as the Sun.

One of the newly anointed largest stars compared to the orbits of planets in our solar system.
The newly crowned largest stars, already known to astronomers as KW Sagitarri, V354 Cephei and KY Cygni, are all in our Milky Way galaxy and within 10,000 light-years of the Sun.
Despite their tremendous diameters, the stars are not the most massive in the universe, said MIT undergraduate student Emily Levesque, who presented the findings.

 The 26 Nearest Stars
Note that this list is continually changing as astronomers discover nearby stars with ever more sensitive detectors in a variety of spectral ranges, especially the infrared, where numerous small stars emit their energy.
Stars are very far apart (average about 8 lightyears for the closest dozen), compared to their size (about 2 lightseconds for the Sun); by a factor of 250 million or so.
Most of the nearby stars are dimmer (higher numbers for absolute magnitude) than our Sun, by factors of 100 to 10,000.

 Bad Astronomy and Universe Today Forum - Discussion: Three Largest Stars Discovered
As the star depletes its supply of hydrogen in the core, its thermal equilibrium becomes unbalanced and the pressure in the star's core lessens.
The star begins to collapse inward because fewer particles means the star cannot maintain the pressure needed to support the star's outer layers.
This collapse increases the pressure and temperature of the core, causing the luminosity of the star's surface to increase.

 Nintendophiles Forums - Three largest stars identified
The three enormous stars from the study are KW Sagitarii (9,800 light-years away), V354 Cephei (9,000 light-years away), and KY Cygni (5,200 light-years away).
The sun is nearly 10,000 degrees F and the hottest known stars are more than 90,000 degrees F. Knowing the temperature was important, Massey said, because a fundamental law of stellar physics holds that a star's brightness is proportional to its temperature and size.
All the stars in the study were normal stars, that is, none were two-star pairs known as binaries, whose parameters could be different.

 Astronomers Discover Largest Stars Known
Figure: The size of KY Cygni, a red supergiant star with one of the largest diameters known, is shown in comparison to Betelgeuse, the brightest star in the constellation of Orion, and one of the largest stars previously known.
The three stars with the largest known sizes are KW Sagitarii (distance 9,800 light-years), V354 Cephei (distance 9,000 light-years), and KY Cygni (distance 5,200 light-years), all with radii about 1500 times that of the Sun, or about 7 astronomical units (AU).
None of the stars in the new study are believed to be binaries, and thus their properties tell us about the extreme sizes that normal stars reach.

 Curious About Astronomy: What is the largest star?
In order to know what the largest star in the universe is we would have had to look at all the stars.
The most massive known is generally accepted to be the Pistol Star, which has a mass about 100-150 times that of the Sun, and is about 10 million times brighter (see this picture).
Red giant stars (like Betelgeuse and Antares) are also very big in volume.When our Sun becomes a red giant in about 5 billion years it will expand to enclose the inner planets.

 Star Types
Looking at a star to determine temperature is not a very scientific way to go about things, so scientists turn to something called a spectrum.
Every chemical element present in a star produces a line in the spectrum and by studying these lines scientists can determine a star's temperature and what the star is made of.
These stars are almost identical to the state that they were born in.
