But in this case, it's called a "dead stellar core" because it no longer has sustained fusion reactions which is what stars are known for, just like a battery that's used up all of its charge is called "Dead" - not because we're assigning human qualities, but because it doesn't do what it's supposed to. Same with any non-living thing that doesn't function as expected being referred to as dead. --[[Special:Contributions/172.69.63.183|172.69.63.183]] 17:41, 19 January 2021 (UTC)</div></td></tr>
