A nova remnant, also known as a "dwarf nova," refers to the aftermath of a stellar explosion that occurs in a binary star system. While the term "nova remnant" is the most commonly used, there are a variety of alternative names that can be used to describe this celestial phenomenon. Some synonyms for "nova remnant" include "cataclysmic variable," which refers to the binary star system in which the explosion occurred, and "planetary nebula," which describes the shape of the explosion debris. Other synonyms include "stella remnant" and "stellar corpse" which imply the post-explosion state of the star. Regardless of the terminology used, a nova remnant marks the end of one star's life and the beginning of a new cycle in the universe.
