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.

Compression (physics)
In mechanics, compression is the application of balanced inward ("pushing") forces to different points on a material or structure, that is, forces with no net sum or torque directed so as to reduce its size in one or more directions.

Density
The density, or more precisely, the volumetric mass density, of a substance is its mass per unit volume.
New!!: Gravitational compression and Density · See more »
Energy
In physics, energy is the quantitative property that must be transferred to an object in order to perform work on, or to heat, the object.
New!!: Gravitational compression and Energy · See more »
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.

Gravity
Gravity, or gravitation, is a natural phenomenon by which all things with mass or energy—including planets, stars, galaxies, and even light—are brought toward (or gravitate toward) one another.

Heat
In thermodynamics, heat is energy transferred from one system to another as a result of thermal interactions.

Kelvin–Helmholtz mechanism
The Kelvin–Helmholtz mechanism is an astronomical process that occurs when the surface of a star or a planet cools.

Main sequence
In astronomy, the main sequence is a continuous and distinctive band of stars that appear on plots of stellar color versus brightness.
New!!: Gravitational compression and Main sequence · See more »
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.
New!!: Gravitational compression and Mass · See more »
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).

Natural satellite
A natural satellite or moon is, in the most common usage, an astronomical body that orbits a planet or minor planet (or sometimes another small Solar System body).

Neutron star
A neutron star is the collapsed core of a large star which before collapse had a total of between 10 and 29 solar masses.
New!!: Gravitational compression and Neutron star · See more »
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).
New!!: Gravitational compression and Nuclear fusion · See more »
Planet
A planet is an astronomical body orbiting a star or stellar remnant that is massive enough to be rounded by its own gravity, is not massive enough to cause thermonuclear fusion, and has cleared its neighbouring region of planetesimals.

Pressure
Pressure (symbol: p or P) is the force applied perpendicular to the surface of an object per unit area over which that force is distributed.
New!!: Gravitational compression and Pressure · See more »
Radiation
In physics, radiation is the emission or transmission of energy in the form of waves or particles through space or through a material medium.

Star
A star is type of astronomical object consisting of a luminous spheroid of plasma held together by its own gravity.

Stellar evolution
Stellar evolution is the process by which a star changes over the course of time.

Sun
The Sun is the star at the center of the Solar System.

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.

Temperature
Temperature is a physical quantity expressing hot and cold.

University of Maryland, College Park
The University of Maryland, College Park (commonly referred to as the University of Maryland, UMD, or simply Maryland) is a public research university located in the city of College Park in Prince George's County, Maryland, approximately from the northeast border of Washington, D.C. Founded in 1856, the university is the flagship institution of the University System of Maryland.
