Giant stars have a much lower surface gravity than do main sequence stars, while the opposite is the case for degenerate, compact stars such as white dwarfs. The surface gravity can influence the appearance of a star's spectrum, with higher gravity causing a broadening of the absorption lines.

White dwarfs are intrinsically very faint because they are so small and, lacking a source of energy production, they fade into oblivion as they gradually cool down.

This fate awaits only those stars with a mass up to about 1. Above that mass, electron pressure cannot support the core against further collapse.

Such stars suffer a different fate as described below. White Dwarfs May Become Novae If a white dwarf forms in a binary or multiple star system, it may experience a more eventful demise as a nova.

Nova is Latin for "new" - novae were once thought to be new stars. Today, we understand that they are in fact, very old stars - white dwarfs.

If a white dwarf is close enough to a companion star, its gravity may drag matter - mostly hydrogen - from the outer layers of that star onto itself, building up its surface layer.

When enough hydrogen has accumulated on the surface, a burst of nuclear fusion occurs, causing the white dwarf to brighten substantially and expel the remaining material.

Within a few days, the glow subsides and the cycle starts again. Sometimes, particularly massive white dwarfs those near the 1.

Supernovae Leave Behind Neutron Stars or Black Holes Main sequence stars over eight solar masses are destined to die in a titanic explosion called a supernova.

A supernova is not merely a bigger nova. In a nova, only the star's surface explodes. In a supernova, the star's core collapses and then explodes.

In massive stars, a complex series of nuclear reactions leads to the production of iron in the core. Having achieved iron, the star has wrung all the energy it can out of nuclear fusion - fusion reactions that form elements heavier than iron actually consume energy rather than produce it.

The star no longer has any way to support its own mass, and the iron core collapses. In just a matter of seconds the core shrinks from roughly miles across to just a dozen, and the temperature spikes billion degrees or more.

The outer layers of the star initially begin to collapse along with the core, but rebound with the enormous release of energy and are thrown violently outward.

Supernovae release an almost unimaginable amount of energy. For a period of days to weeks, a supernova may outshine an entire galaxy.

Likewise, all the naturally occurring elements and a rich array of subatomic particles are produced in these explosions.

On average, a supernova explosion occurs about once every hundred years in the typical galaxy. About 25 to 50 supernovae are discovered each year in other galaxies, but most are too far away to be seen without a telescope.

Neutron Stars If the collapsing stellar core at the center of a supernova contains between about 1. Neutron stars are incredibly dense - similar to the density of an atomic nucleus.

Because it contains so much mass packed into such a small volume, the gravitation at the surface of a neutron star is immense.

Like the White Dwarf stars above, if a neutron star forms in a multiple star system it can accrete gas by stripping it off any nearby companions.

The Rossi X-Ray Timing Explorer has captured telltale X-Ray emissions of gas swirling just a few miles from the surface of a neutron star.

Neutron stars also have powerful magnetic fields which can accelerate atomic particles around its magnetic poles producing powerful beams of radiation.

Those beams sweep around like massive searchlight beams as the star rotates. If such a beam is oriented so that it periodically points toward the Earth, we observe it as regular pulses of radiation that occur whenever the magnetic pole sweeps past the line of sight.

In this case, the neutron star is known as a pulsar. Black Holes If the collapsed stellar core is larger than three solar masses, it collapses completely to form a black hole: an infinitely dense object whose gravity is so strong that nothing can escape its immediate proximity, not even light.

Since photons are what our instruments are designed to see, black holes can only be detected indirectly. Indirect observations are possible because the gravitational field of a black hole is so powerful that any nearby material - often the outer layers of a companion star - is caught up and dragged in.

The result is a supernova. Gravity causes the core to collapse, making the core temperature rise to nearly 18 billion degrees F 10 billion degrees C , breaking the iron down into neutrons and neutrinos.

In about one second, the core shrinks to about six miles 10 km wide and rebounds just like a rubber ball that has been squeezed, sending a shock wave through the star that causes fusion to occur in the outlying layers.

The star then explodes in a so-called Type II supernova. If the remaining stellar core was less than roughly three solar masses large, it becomes a neutron star made up nearly entirely of neutrons, and rotating neutron stars that beam out detectable radio pulses are known as pulsars.

If the stellar core was larger than about three solar masses, no known force can support it against its own gravitational pull, and it collapses to form a black hole.

A low-mass star uses hydrogen fuel so sluggishly that they can shine as main-sequence stars for billion to 1 trillion years — since the universe is only about Still, astronomers calculate these stars, known as red dwarfs , will never fuse anything but hydrogen, which means they will never become red giants.

Instead, they should eventually just cool to become white dwarfs and then black dwarves. Although our solar system only has one star, most stars like our sun are not solitary, but are binaries where two stars orbit each other, or multiples involving even more stars.

In fact, just one-third of stars like our sun are single, while two-thirds are multiples — for instance, the closest neighbor to our solar system, Proxima Centauri , is part of a multiple system that also includes Alpha Centauri A and Alpha Centauri B.

Still, class G stars like our sun only make up some 7 percent of all stars we see — when it comes to systems in general, about 30 percent in our galaxy are multiple , while the rest are single, according to Charles J.

Lada of the Harvard-Smithsonian Center for Astrophysics. Binary stars develop when two protostars form near each other. One member of this pair can influence its companion if they are close enough together, stripping away matter in a process called mass transfer.

If one of the members is a giant star that leaves behind a neutron star or a black hole, an X-ray binary can form, where matter pulled from the stellar remnant's companion can get extremely hot — more than 1 million F , C and emit X-rays.

If a binary includes a white dwarf, gas pulled from a companion onto the white dwarf's surface can fuse violently in a flash called a nova.

At times, enough gas builds up for the dwarf to collapse, leading its carbon to fuse nearly instantly and the dwarf to explode in a Type I supernova, which can outshine a galaxy for a few months.

Astronomers describe star brightness in terms of magnitude and luminosity. The magnitude of a star is based on a scale more than 2, years old, devised by Greek astronomer Hipparchus around BC.

He numbered groups of stars based on their brightness as seen from Earth — the brightest ones were called first magnitude stars, the next brightest were second magnitude, and so on up to sixth magnitude, the faintest visible ones.

Nowadays astronomers refer to a star's brightness as viewed from Earth as its apparent magnitude, but since the distance between Earth and the star can affect the light one sees from it, they now also describe the actual brightness of a star using the term absolute magnitude, which is defined by what its apparent magnitude would be if it were 10 parsecs or The magnitude scale now runs to more than six and less than one, even descending into negative numbers — the brightest star in the night sky is Sirius , with an apparent magnitude of Luminosity is the power of a star — the rate at which it emits energy.

Although power is generally measured in watts — for instance, the sun's luminosity is trillion trillion watts— the luminosity of a star is usually measured in terms of the luminosity of the sun.

For example, Alpha Centauri A is about 1. To figure out luminosity from absolute magnitude, one must calculate that a difference of five on the absolute magnitude scale is equivalent to a factor of on the luminosity scale — for instance, a star with an absolute magnitude of 1 is times as luminous as a star with an absolute magnitude of 6.

Stars come in a range of colors, from reddish to yellowish to blue. The color of a star depends on surface temperature.

A star might appear to have a single color, but actually emits a broad spectrum of colors, potentially including everything from radio waves and infrared rays to ultraviolet beams and gamma rays.

Different elements or compounds absorb and emit different colors or wavelengths of light, and by studying a star's spectrum, one can divine what its composition might be.

Astronomers measure star temperatures in a unit known as the kelvin , with a temperature of zero K "absolute zero" equaling minus A dark red star has a surface temperature of about 2, K 2, C and 4, F ; a bright red star, about 3, K 3, C and 5, F ; the sun and other yellow stars, about 5, K 5, C and 9, F ; a blue star, about 10, K 9, C and 17, F to 50, K 49, C and 89, F.

The surface temperature of a star depends in part on its mass and affects its brightness and color. Specifically, the luminosity of a star is proportional to temperature to the fourth power.

For instance, if two stars are the same size but one is twice as hot as the other in kelvin, the former would be 16 times as luminous as the latter.

Astronomers generally measure the size of stars in terms of the radius of our sun. For instance, Alpha Centauri A has a radius of 1.

Stars range in size from neutron stars, which can be only 12 miles 20 kilometers wide, to supergiants roughly 1, times the diameter of the sun.

The size of a star affects its brightness. Specifically, luminosity is proportional to radius squared.

For instance, if two stars had the same temperature, if one star was twice as wide as the other one, the former would be four times as bright as the latter.

Astronomers represent the mass of a star in terms of the solar mass , the mass of our sun.
