Physicists have theorized the existence of new types of celestial objects that they name “nestars.”

These are gravitational condensate stars, or gravastars, nestled among other gravitational condensate stars, like a Russian matryoshka doll, or nesting doll.

This type of doll is distinguished by its hollow, round form and the ability to be split apart to reveal a sequence of increasingly smaller dolls nestled inside.
