Apparent magnitude
The apparent magnitude of a celestial object is a number that is a measure of its brightness as seen by an observer on Earth.
Apparent magnitude and Astronomy · Apparent magnitude and Main sequence ·
Black hole
A black hole is a region of spacetime exhibiting such strong gravitational effects that nothing—not even particles and electromagnetic radiation such as light—can escape from inside it.
Astronomy and Black hole · Black hole and Main sequence ·
CNO cycle
The CNO cycle (for carbon–nitrogen–oxygen) is one of the two known sets of fusion reactions by which stars convert hydrogen to helium, the other being the proton–proton chain reaction.

Convection zone
A convection zone, convective zone or convective region of a star is a layer which is unstable to convection.

Dwarf star
A dwarf star is a star of relatively small size and low luminosity.

Earth
Earth is the third planet from the Sun and the only astronomical object known to harbor life.
Astronomy and Earth · Earth and Main sequence ·
Gravitational collapse
Gravitational collapse is the contraction of an astronomical object due to the influence of its own gravity, which tends to draw matter inward toward the center of gravity.

Helium
Helium (from lit) is a chemical element with symbol He and atomic number 2.
Astronomy and Helium · Helium and Main sequence ·
Hydrogen
Hydrogen is a chemical element with symbol H and atomic number 1.
Astronomy and Hydrogen · Hydrogen and Main sequence ·
Initial mass function
In astronomy, the initial mass function (IMF) is an empirical function that describes the initial distribution of masses for a population of stars.
Astronomy and Initial mass function · Initial mass function and Main sequence ·
Interstellar medium
In astronomy, the interstellar medium (ISM) is the matter and radiation that exists in the space between the star systems in a galaxy.
Astronomy and Interstellar medium · Interstellar medium and Main sequence ·
Jeans instability
In stellar physics, the Jeans instability causes the collapse of interstellar gas clouds and subsequent star formation.
Astronomy and Jeans instability · Jeans instability and Main sequence ·
Jupiter
Jupiter is the fifth planet from the Sun and the largest in the Solar System.
Astronomy and Jupiter · Jupiter and Main sequence ·
Kelvin
The Kelvin scale is an absolute thermodynamic temperature scale using as its null point absolute zero, the temperature at which all thermal motion ceases in the classical description of thermodynamics.
Astronomy and Kelvin · Kelvin and Main sequence ·
Mass
Mass is both a property of a physical body and a measure of its resistance to acceleration (a change in its state of motion) when a net force is applied.
Astronomy and Mass · Main sequence and Mass ·
Metallicity
In astronomy, metallicity is used to describe the abundance of elements present in an object that are heavier than hydrogen or helium.
Astronomy and Metallicity · Main sequence and Metallicity ·
Molecular cloud
A molecular cloud, sometimes called a stellar nursery (if star formation is occurring within), is a type of interstellar cloud, the density and size of which permit the formation of molecules, most commonly molecular hydrogen (H2).
Astronomy and Molecular cloud · Main sequence and Molecular cloud ·
Nuclear fusion
In nuclear physics, nuclear fusion is a reaction in which two or more atomic nuclei come close enough to form one or more different atomic nuclei and subatomic particles (neutrons or protons).
Astronomy and Nuclear fusion · Main sequence and Nuclear fusion ·
Parallax
Parallax is a displacement or difference in the apparent position of an object viewed along two different lines of sight, and is measured by the angle or semi-angle of inclination between those two lines.
Astronomy and Parallax · Main sequence and Parallax ·
Photosphere
The photosphere is a star's outer shell from which light is radiated.
Astronomy and Photosphere · Main sequence and Photosphere ·
Protostar
A protostar is a very young star that is still gathering mass from its parent molecular cloud.
Astronomy and Protostar · Main sequence and Protostar ·
Radiation zone
A radiation zone, radiative zone or radiative region is a layer of a star's interior where energy is primarily transported toward the exterior by means of radiative diffusion and thermal conduction, rather than by convection.
Astronomy and Radiation zone · Main sequence and Radiation zone ·
Red giant
A red giant is a luminous giant star of low or intermediate mass (roughly 0.3–8 solar masses) in a late phase of stellar evolution.
Astronomy and Red giant · Main sequence and Red giant ·
Spectral line
A spectral line is a dark or bright line in an otherwise uniform and continuous spectrum, resulting from emission or absorption of light in a narrow frequency range, compared with the nearby frequencies.
Astronomy and Spectral line · Main sequence and Spectral line ·
Star
A star is type of astronomical object consisting of a luminous spheroid of plasma held together by its own gravity.
Astronomy and Star · Main sequence and Star ·
Star cluster
Star clusters are groups of stars.
Astronomy and Star cluster · Main sequence and Star cluster ·
Stellar classification
In astronomy, stellar classification is the classification of stars based on their spectral characteristics.
Astronomy and Stellar classification · Main sequence and Stellar classification ·
Stellar evolution
Stellar evolution is the process by which a star changes over the course of time.
Astronomy and Stellar evolution · Main sequence and Stellar evolution ·
Sun
The Sun is the star at the center of the Solar System.
Astronomy and Sun · Main sequence and Sun ·
Supernova
A supernova (plural: supernovae or supernovas, abbreviations: SN and SNe) is a transient astronomical event that occurs during the last stellar evolutionary stages of a star's life, either a massive star or a white dwarf, whose destruction is marked by one final, titanic explosion.
Astronomy and Supernova · Main sequence and Supernova ·
Variable star
A variable star is a star whose brightness as seen from Earth (its apparent magnitude) fluctuates.
Astronomy and Variable star · Main sequence and Variable star ·
White dwarf
A white dwarf, also called a degenerate dwarf, is a stellar core remnant composed mostly of electron-degenerate matter.

61 Cygni
61 Cygni Not to be confused with 16 Cygni, a more distant system containing two G-type stars harboring the gas giant planet 16 Cygni Bb.
