Stellar Sources Most Referenced In Astronomical Literature

Ordering sources by "times people have written about them" makes a pretty good allsorts selection of interesting celestial objects. I've excluded background galaxies/quasars from this list to focus on stars or stellar remnants. A few dozen of the brightest stars in Earth's night sky are not represented in Gaia EDR3 data; these, where they appear in the list, have dashes for their Gaia designation.

(Reference counts are SIMBAD's as of January 2022. Gaia designations are from EDR3.)
