These studies suggest that the number of dead stars we see is extremely rare.
The question of how many of the stars we see are dead is a fascinating one, touching on the life cycles of stars and the evolution of our galaxy. Stars, like all celestial objects, have finite lifespans, and many of the stars that once shone brightly in our night sky have since exhausted their nuclear fuel and transitioned into different states.

In summary, about 12% of the stars in our solar neighborhood are dead, having exhausted their hydrogen and left the main sequence. These stars were, on average, significantly more massive than the average main-sequence star. However, the remnants of these dead stars are not commonly observed, indicating that they may not exist in a form that is easily detectable.
