Can you actually buy a star?

Can you really purchase a star in the vast expanse of the night sky? The concept seems almost surreal, akin to purchasing a piece of the moon or the sun. Is this a legitimate transaction, or merely a figment of imagination? If indeed it is possible, what would be the process? Would I be able to name it, perhaps dedicate it to a loved one? What kind of authority or organization would facilitate such a transaction? Moreover, would this simply be a symbolic gesture, or would I actually acquire some sort of ownership rights over the star? Surely, this must be a highly specialized field, requiring intricate knowledge and perhaps even a hefty price tag. I'm curious to know if this is a feasible option for those who wish to leave their mark on the universe.
