Is there a list of stars that we cannot see anymore because they have burned out?
-------------------------------------------------------
answers:
Zardoz say: Yes, SN 393. It is the only naked-eye visible star that has gone nova in human history. All other supernova in human history happened to stars that wouldn't have been visible due to their distance.

PhotonX say: No. You can find lists of neutron stars, and suspected (and confirmed) black holes, and lists of white dwarfs. As far as I know the Universe isn't old enough for black dwarfs, which would be truly burned-out stars, but we would have no way of detecting the vast majority of them even if they did exist.

jocelyn say: Yes, the nebula that formed after large stars burned out are named and listed. Earth is believed to have got its precious/heavy minerals from a nebula such as the Crab Nebula.

Starrysky say: We know of a supernova remnant in Cassiopeia that exploded about 415 years ago, only because of the accurate charting of Tycho Brahe at that time. Not much of the star left now, not sure if it has been spotted and confirmed, analyzed. Search Google for it.
Just a bit of star left in LMC from the 1987 supernova, but we can pick it out.
We can see the remnant of the explosion creating the 965 year old Crab Nebula in Taurus; it is a flashing optical pulsar.
There are quite a few planetary nebulae like M57 in Lyra, with a tiny faint star in the center. There are a lot of other planetaries where we cannot see anything that formed them. But the list of those has no stars associated with them as observed and named and numbered since we cannot see them now.
Any smaller stars that did not explode (or not very much) did shrink down to white dwarf stars like Sirius B.
We can still see those.
A very few that exploded and collapsed into black holes cannot be seen of course. We know there are many, especially at center of most large galaxies. There is a radio energy "picture" of one. No star image though.

say: if we can't see them, how would we know about them? except for some supernovas, most of which happen in galaxies far far away, nearly all burned out stars did their burning out tens of millions of years before humans walked the earth. you can still observe the remnants of some exploded supernovas within our galaxy with a good telescope. the crab nebula is one good example.

say: Yes but I do not know their names.
