Do stars have ghosts?

Again, as the title of the post begins with a question, I'm sad to say the answer is no. Stars do not have ghosts. But what does happen to a star after death? Well it depends entirely on the type of star in question. For example, our very own sun will eventually run out of hydrogen fuel to fuse. Once this fusion process halts, the weight of the star will cause it to collapse under its own weight. However, such a contraction drives up the temperature of the star, causing the outer layers to expand and our sun will become a red giant. Unfortunately for any life that may exist when this occurs, the radius of the sun will at that point grow beyond the orbit of the earth and everything we've ever known and loved will be immolated by the very thing that once gave us life. Pretty morbid right? Well there's a silver lining: odds are we'll be extinct by then, and if not, we'll have (hopefully) found a way to other star systems! And the fun doesn't stop there! Eventually the core of the new sun will get hot enough to start fusing helium gas into carbon. Eventually the core will again run out of fuel, and the outer layers will expand into a planetary nebula, making our humble solar system a sight to behold from other worlds. Finally, our sun will cool and the only remaining facet: the core, will become a glowing speck known as a white dwarf. If we're lucky, the core of carbon may cool enough to crystalize, turning the once ball of life-giving plasma into a planet-sized diamond, forever drifting through the cosmos, an eternal reminder of the system that we once called home.

So in a sense, you could say that while stars don't have souls to remain after death, they do have aspects that can remain for billions of years. Who knows, maybe the white dwarves we've observed once housed a system with beings just like us? And now all we see is a... ghost?
