| Feb 7, 2019 at 15:02 | comment | added | PM 2Ring | A neutron-degenerate remnant, aka a neutron star, remains after a star explodes, scattering all sorts of goodies into the interstellar medium. There are several different types of supernova, the Wikipedia article is a good comprehensive introduction to the topic. | |
| Feb 7, 2019 at 14:57 | comment | added | PM 2Ring | "a stellar remnant lower in mass than all of those". There's no such animal. Small stars eventually turn into white dwarfs. At least, we think they do, the universe isn't old enough yet for us to see what happens to red dwarfs when they stop doing fusion. Those things probably burn for a trillion years or more. And white dwarfs take like 50 billion years to cool down. | |
| Feb 7, 2019 at 14:43 | comment | added | P Varga | Ok so I've read up about this and it looks like stars that are massive enough to produce iron form a neutron-degenerate remnant, and stars that are less massive and don't produce iron still form an electron-degenerate remnant ‹white dwarf›. I digress but how was the iron in the Universe produced then? | |

| Feb 7, 2019 at 13:42 | comment | added | P Varga | Sorry I used the vague term because I didn't know the name of what I was referring to. I meant a stellar remnant lower in mass than all of those (if that's possible at all) | |

| Feb 7, 2019 at 10:33 | comment | added | AtmosphericPrisonEscape | This may be a good question if you don't know anything about stellar remnants. Therefore I upvote. But still, the prior research suggested by Chappo would be welcome. | |

| Feb 7, 2019 at 6:36 | comment | added | Chappo Hasn't Forgotten | By "stellar remnant", do you mean a white dwarf, a neutron star or a black hole? You might like to look them up (e.g. on Wikipedia) to see how utterly unlike a planet they each are, whether in composition, density or the nature of the degeneracy of the core. You might do best to focus on white dwarfs, as neutron stars and black holes aren't composed of "elements". | |
