| dbo:abstract | Xi Aurigae (ξ Aur / ξ Aurigae) è una stella bianca nella sequenza principale di magnitudine 4,97 situata nella costellazione dell'Auriga. Dista 241 anni luce dal sistema solare. (it) Xi Aurigae, Latinized from ξ Aurigae, is the Bayer designation for a single, white-hued star in the northern constellation of Auriga. This star was once considered part of the constellation of Camelopardalis and held the Flamsteed designation 32 Camelopardalis. It is visible to the naked eye with an apparent visual magnitude of +5.0. The measured annual parallax shift of this star is 13.69 ± 0.28 mas, which corresponds to a physical distance of 238 light-years (73 parsecs) with a 5 light-year margin of error. At that distance, the visual magnitude of the star is diminished by an extinction of 0.108 due to interstellar dust. This is an A-type main sequence star with a stellar classification of A2 Va. Although it was one of the first stars to be cataloged as a Lambda Boötis star, Murphy et al. (2015) don't consider it to be a member of this population. The star has nearly twice the mass of the Sun and about 1.1 times the Sun's radius. It is an estimated 174 million years old and is spinning with a projected rotational velocity of 62 km/s. Xi Aurigae is radiating 49.5 times the Sun's luminosity from its photosphere at an effective temperature of around 9,152 K. (en) Xi Aurigae (30 Aurigae) é uma estrela na direção da constelação de Auriga. Possui uma ascensão reta de 05h 54m 50.79s e uma declinação de +55° 42′ 24.9″. Sua magnitude aparente é igual a 4.96. Considerando sua distância de 241 anos-luz em relação à Terra, sua magnitude absoluta é igual a 0.62. Pertence à classe espectral A2V. (pt) Xi Aurigae (ξ Aurigae, förkortat Xi Aur, ξ Aur) som är stjärnans Bayerbeteckning, är en ensam stjärna belägen i den norra delen av stjärnbilden Kusken. Den har en skenbar magnitud på 5,00 och är synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 13,69 mas, beräknas den befinna sig på ett avstånd på ca 238 ljusår (ca 73 parsek) från solen. På det beräknade avståndet minskas stjärnans skenbara magnitud genom skymning med 0,108 enheter på grund av interstellärt stoft.
