V 347 Pup

An Eclipsing Cataclysmic Variable Star

V347 Pup is a cataclysmic variable star located in the constellation Puppis. It is a close binary system consisting of a white dwarf and a secondary star, which transfers material onto the white dwarf through an accretion disk. The system shows deep eclipses, making it well-suited for detailed observational studies. Its orbital period is approximately 5.57 hours. Due to its brightness and disk structure, V347 Pup is often used to study accretion processes and the evolution of cataclysmic variables.
