A '''black dwarf''' was a rare [[Star/Legends|compact star]] and one endpoint of stellar evolution. [[White dwarf/Legends|White dwarf]] [[Dwarf star/Legends|stars]] that were once [[giant star]]s decayed into [[Color/Legends|black]] dwarfs after burning all of their [[Hydrogen/Legends|fuel]] and then [[Temperature/Legends|cooling]]. [[The Ring/Legends|"The Ring,"]] a black dwarf surrounded by highly ionized, [[Radiation/Legends|radioactive]] green gas, could be found in the [[Outer Rim Territories/Legends|Outer Rim's]] [[Anoat sector/Legends|Anoat sector]].

==Description==
A black dwarf was a type of [[Dwarf star/Legends|dwarf star]]<ref name="GG8" /> classified as a [[Star/Legends|compact star]], representing the endpoint of stellar evolution.<ref name="Atlas" /> A [[giant star]] that exhausted all of its [[Hydrogen/Legends|hydrogen]] [[Fuel/Legends|fuel]] could collapse into a [[White dwarf/Legends|white dwarf]], which in very rare instances<ref name="GG8" />&mdash;making for less than one percent of all stars in [[The galaxy/Legends|the galaxy]]<ref name="Atlas" />&mdash;could then become a [[Color/Legends|black]] dwarf as the core of the star [[Temperature/Legends|cooled]]. Remnant dust clouds with unusual chemical elements could potentially coalesce around the area of the star.<ref name="GG8" /> Black dwarfs were unlikely to support life.<ref name="Atlas" />

==History==
Eons before the [[Galactic Civil War/Legends|Galactic Civil War]],<ref name="Galactic Gazetteer">{{WizardsCite|url=default.asp?x=starwars/article/sw20040325web|text=Galactic Gazetteer: Hoth and the Greater Javin|int=Galactic Gazetteer: Hoth and the Greater Javin|archivedate=20100508024939}}</ref> which was fought between the [[Galactic Empire/Legends|Galactic Empire]] and the [[Alliance to Restore the Republic/Legends|Rebel Alliance]] between [[2 BBY/Legends|2 BBY]] and [[4 ABY/Legends|4 ABY]],<ref name="Atlas" /> a star located in the [[Anoat sector/Legends|Anoat sector]] of the [[Outer Rim Territories/Legends|Outer Rim Territories]] [[Supernova/Legends|exploded]] and eventually decayed into a black dwarf. Locals of the [[Greater Javin/Legends|Greater Javin]] region knew this star as [[The Ring/Legends|"the Ring"]] for the highly ionized, [[Radiation/Legends|radioactive]] green gas that surrounded it. What remained of the Ring's supernova took shape as the [[Twin Nebulae]], vast [[Nebula/Legends|clouds]] of glittering gas and dust that for [[Standard century/Legends|centuries]] hampered regional [[Hyperspace/Legends|hyperspace]] [[Scout/Legends|exploration]].<ref name="Galactic Gazetteer" />

==Behind the scenes==
The [[1993]] [[West End Games]] sourcebook ''[[Galaxy Guide 8: Scouts]]'', part of ''[[Star Wars: The Roleplaying Game]]'', first introduced the concept of black dwarfs to the ''[[Star Wars]]'' universe.<ref name="GG8" /> "[[Galactic Gazetteer: Hoth and the Greater Javin]]," a [[2004]] supplement for [[Wizards of the Coast]]'s ''[[Star Wars Roleplaying Game]]'', later established the existence of the Ring, the only example of a black dwarf in the [[Star Wars Legends|''Star Wars'' Legends]] [[Canon|continuity]].<ref name="Galactic Gazetteer" /> The subsequent [[2009]] reference book ''[[The Essential Atlas]]'' mapped out the black dwarf's placement in the ''Star Wars'' version of [[Wikipedia:Stellar evolution|stellar evolution]],<ref name="Atlas" /> which mirrors the real-world equivalent, including the stages of the [[Wikipedia:Main sequence|main sequence]].<ref name="Stellar Evolution">{{Cite_web|url=http://www.universetoday.com/24643/star-main-sequence|title=Star Main Sequence|author=Cain, Fraser|date=2016-04-26|work=[[Wikipedia:Universe Today|Universe Today]]|publisher=Fraser Cain|archivedate=20160303212456}}</ref>

In real-world [[Wikipedia:Astronomy|astronomy]], a [[Wikipedia:Black dwarf|black dwarf]] is the theoretical endpoint of stellar evolution, wherein a [[Wikipedia:White dwarf|white dwarf]] has cooled sufficiently that it no longer emits visible light. Scientists do not expect that any black dwarfs yet exist in the [[Wikipedia:Universe|universe]], since the calculated time for a white dwarf to transition into a black dwarf exceeds the current [[Wikipedia:Age of the universe|age of the universe]], at nearly 14 billion years.<ref name="Space.com">{{Cite_web|url=http://www.space.com/23799-black-dwarfs.html|title=Black Dwarf Stars: The (Theoretical) End of Stellar Evolution|author=Redd, Nola Taylor|date=2013-12-02, 1:53 pm ET|work=[[Wikipedia:Space.com|Space.com]]|publisher=[[Wikipedia:Purch Group|Purch]]|archivedate=20160506052514}}</ref>
