Definitions of ACCRETION

1. The act of increasing by natural growth; especially the increase of organic bodies by the internal accession of parts; organic growth.
2. The act of increasing, or the matter added, by an accession of parts externally; an extraneous addition.
3. Something added externally to promote the external growth of an item.
4. Concretion; coherence of separate particles.
5. (biology) A growing together of parts naturally separate, as of the fingers or toes.
6. (geology) The gradual increase of land by deposition of water-borne sediment.
7. (legal) The adhering of property to something else, by which the owner of one thing becomes possessed of a right to another; generally, gain of land by the washing up of sand or soil from the sea or a river, or by a gradual recession of the water from the usual watermark.
8. (legal) Gain to an heir or legatee; failure of a coheir to the same succession, or a co-legatee of the same thing, to take his share percentage.
9. (astrophysics) The formation of planets and other bodies by collection of material through gravity.
10. (conservation) Built-up matter lying on top of, rather than embedded in, a surface.

Examples of Using ACCRETION in a Sentence

• The Eddington limit, the natural limit to the luminosity of stars, or the radiation generated by accretion onto a compact object, is named in his honour.
• The emission from an AGN is powered by a supermassive black hole with a mass ranging from millions to tens of billions of solar masses, surrounded by a gaseous accretion disc.
• The belt lies within a zone that has been geologically active at intervals beginning from near the time of crustal accretion in central Colorado at least 1.
• It is hypothesised that the accretion of Earth began soon after the formation of the calcium-aluminium-rich inclusions and the meteorites.
• 23 Ga by accretion and collision of fragments produced by breakup of an older supercontinent, Columbia, assembled by global-scale 2.
• The verses are attributed to Odin; the implicit attribution to Odin facilitated the accretion of various mythological material also dealing with the same deity.
• Oberon likely formed from the accretion disk that surrounded Uranus just after the planet's formation.
• The latter may be due to slowing down (below stall speed) or the accretion of ice on the wings (especially if the ice is rough).
• An example is Breedon on the Hill in Leicestershire, whose name seems to have grown by the accretion of elements from three different languages at different times in its history, all emphasising the hill.
• Strong UV and X-ray emission is often detected from the accretion disc, powered by the loss of gravitational potential energy from the infalling material.
• Cylindrical coordinates are useful in connection with objects and phenomena that have some rotational symmetry about the longitudinal axis, such as water flow in a straight pipe with round cross-section, heat distribution in a metal cylinder, electromagnetic fields produced by an electric current in a long, straight wire, accretion disks in astronomy, and so on.
• The non-stellar radiation from an AGN is theorized to result from the accretion of matter by a supermassive black hole at the center of its host galaxy.
• Type I bursts are caused by thermonuclear runaway, while type II arise from the release of gravitational (potential) energy liberated through accretion.
• Some strong x-ray flares have been observed, presumably related to changes in the accretion disc, but no correlations have been found with the strong optical variations.
• Accretion (meteorology), the process by which water vapor in clouds forms water droplets around nucleation sites.
• Between these episodes, when the accretion is absent, SXTs are usually very faint, or even unobservable; this is called the "quiescent" state.
• Accretion of gas onto the star continues for another 10 million years, before the disk disappears, perhaps being blown away by the young star's stellar wind, or perhaps simply ceasing to emit radiation after accretion has ended.
• Here the idea appeared that these objects might be low-mass stars surrounded by an evaporating protostellar accretion disk.
• The building of the harbor near the fort resulted in sand accretion to the south of the fort and the harbor and the sea, which was washing the ramparts of the fort, moved afar at about 2.
• The other means of acquiring territory are conquest, cession by agreement, accretion through the operations of nature, and prescription through the continuous exercise of sovereignty.
• The shoreline moves toward the island (or detached breakwater) owing to the accretion of sand in the lee of the island, where wave energy and longshore drift are reduced and therefore deposition of sand occurs.
• Nuclear energy makes use of Earth's mineral deposits of fissionable elements, while geothermal power utilizes the Earth's internal heat, which comes from a combination of residual heat from planetary accretion (about 20%) and heat produced through radioactive decay (80%).
• The icing Research Tunnel is a wind tunnel capable of simulating atmospheric icing condition to test the effect of ice accretion on aircraft wings and body as well as to test anti-icing systems for aircraft.
• His research on quasars has included development of the relativistic blast wave model for variability, introduction of reverberation mapping to analyze variable emission line profiles, the two-phase model for quasar emission line regions, and the development of the theory of coronae and winds from accretion disks.
• This has important uses all over astronomy, from detecting binary stars, exoplanets, compact objects such as neutron stars and black holes (by the motion of hydrogen in accretion disks around them), identifying groups of objects with similar motions and presumably origins (moving groups, star clusters, galaxy clusters, and debris from collisions), determining distances (actually redshifts) of galaxies or quasars, and identifying unfamiliar objects by analysis of their spectrum.
