A star is a massive, luminous sphere of plasma held together by
gravity. At the end of its lifetime, a star can also contain a
proportion of degenerate matter. The nearest star to Earth is the Sun,
which is the source of most of the energy on Earth. Other stars are
visible from Earth during the night, when they are not obscured by
atmospheric phenomena, appearing as a multitude of fixed luminous points
because of their immense distance. Historically, the most prominent
stars on the celestial sphere were grouped together into constellations
and asterisms, and the brightest stars gained proper names. Extensive
catalogues of stars have been assembled by astronomers, which provide
standardized star designations.
For at least a portion of its life, a star shines due to
thermonuclear fusion of hydrogen in its core releasing energy that
traverses the star’s interior and then radiates into outer space.
Almost all naturally occurring elements heavier than helium were
created by stars, either via stellar nucleosynthesis during their
lifetimes or by supernova nucleosynthesis when stars explode.
Astronomers can determine the mass, age, chemical composition and many
other properties of a star by observing its spectrum, luminosity and
motion through space. The total mass of a star is the principal
determinant in its evolution and eventual fate. Other characteristics of
a star are determined by its evolutionary history, including diameter,
rotation, movement and temperature. A plot of the temperature of many
stars against their luminosities, known as a HertzsprungÂRussell
diagram (HÂR diagram), allows the age and evolutionary state of a star
to be determined.
A star begins as a collapsing cloud of material composed primarily
of hydrogen, along with helium and trace amounts of heavier elements.
Once the stellar core is sufficiently dense, some of the hydrogen is
steadily converted into helium through the process of nuclear fusion.
The remainder of the star’s interior carries energy away from the core
through a combination of radiative and convective processes. The star’s
internal pressure prevents it from collapsing further under its own
gravity. Once the hydrogen fuel at the core is exhausted, a star with at
least 0.4 times the mass of the Sun expands to become a red giant, in
some cases fusing heavier elements at the core or in shells around the
core. The star then evolves into a degenerate form, recycling a portion
of the matter into the interstellar environment, where it will form a
new generation of stars with a higher proportion of heavy elements.
