Ellipsoidal variable stars (ELL) are binary systems with two stars deformed by the mutual gravitational attraction, that typically rotate around each other in short periods. We have discovered the variability of the binary star system called GUNVAG1 with AAVSO UID 000-BNJ-506/VSX 1500078, located in the Auriga constellation at coordinates J051227.25 +333449.8, and we have determined the characterizing parameters. GUNVAG1 resulted to be an ELL binary star system with a period of 0.358 days ≈ 8.6 hours. The distance of the GUNVAG1 system from Earth is 2220 ± 130 pc ≈ 7240 ± 430 ly

Abstract
Ellipsoidal variable stars (ELL) are binary systems with two stars deformed by the mutual gravitational attraction, that typically rotate around each other in short periods. We have discovered the variability of the binary star system called GUNVAG1 with AAVSO UID 000-BNJ-506/VSX 1500078, located in the Auriga constellation at coordinates J051227.25 +333449.8, and we have determined the characterizing parameters. GUNVAG1 resulted to be an ELL binary star system with a period of 0.358 days ≈ 8.6 hours. The distance of the GUNVAG1 system from Earth is 2220 ± 130 pc ≈ 7240 ± 430 ly
