About: HD 115337

An Entity of Type: star, from Named Graph: http://dbpedia.org, within Data Space: dbpedia.org

HD 115337 is a binary star located in the northern circumpolar constellation Camelopardalis. The pair have a combined apparent magnitude of 6.25, placing it near the limit for naked eye visibility. Parallax measurements place the system at a distance of 698 light years. It has a heliocentric radial velocity of −9.4 km/s, indicating that it is drifting towards the Solar System.

  • HD 115337 is a binary star located in the northern circumpolar constellation Camelopardalis. The pair have a combined apparent magnitude of 6.25, placing it near the limit for naked eye visibility. Parallax measurements place the system at a distance of 698 light years. It has a heliocentric radial velocity of −9.4 km/s, indicating that it is drifting towards the Solar System. The components have spectral classifications of K0 Ib and A8 V, indicating a K-type lower luminosity supergiant and an A-type main-sequence star (with uncertainty). At present the primary has 3.4 times the mass of the Sun and an enlarged radius of 16.4 R☉ due to its evolved status. It radiates 161 times the luminosity of the Sun from its photosphere at an effective temperature of 5,160 K, giving a yellowish orange hue. HD 115337A is metal deficent, having an iron abundance only 74% of solar levels. Like most giants, it spins slowly with a projected rotational velocity of less than 1 km/s. Ironically, the characteristics of HD 115337A belong to a giant star as opposed to a supergiant. It has even been classified as G5 III or G8 III, more consistent with the above properties. Nevertheless, optical measurements from Mason et al. (2001) find the pair to have a mean separation of an arcsecond along a position angle of 184°. (en)
  • HD 115337 är en dubbelstjärna i den norra delen av stjärnbilden Giraffen. Den har en skenbar magnitud av ca 6,25 och är mycket svagt synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 4,8 mas, beräknas den befinna sig på ett avstånd på ca 680 ljusår (ca 210 parsek) från solen. Den rör sig närmare solen med en heliocentrisk radialhastighet på ca -9 km/s. (sv)
