About: 16 Sagittarii

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

16 Sagittarii is a multiple star system in the southern zodiac constellation of Sagittarius. It is near the lower limit of brightness for stars that can be seen with the naked eye, having an apparent visual magnitude of 6.02. The estimated distance to this system is about 4,600 light years. It is a member of the Sgr OB7 cluster. Along with the O-type star 15 Sgr, it is ionizing an H II region along the western edge of the molecular cloud L291.

  • 16 Sagittarii is a multiple star system in the southern zodiac constellation of Sagittarius. It is near the lower limit of brightness for stars that can be seen with the naked eye, having an apparent visual magnitude of 6.02. The estimated distance to this system is about 4,600 light years. It is a member of the Sgr OB7 cluster. Along with the O-type star 15 Sgr, it is ionizing an H II region along the western edge of the molecular cloud L291. Mason et al. (1998) found this to be a member of a speckle binary with an estimated orbital period of roughly 130 years and a magnitude difference of 0.4. Both components show indications of a variable radial velocity, suggesting that they are spectroscopic binaries – making it a candidate quadruple star system. However, Tokovinin (2008) considers it a triple star system. Orbital elements for the main spectroscopic binary, components Aa and Ab, were published by Mayer et al. (2014), giving an orbital period of 12.76 days and an eccentricity of 0.18. This system displays a merged stellar classification of O9.5 III, matching a blue-hued O-type giant star. It shows a longitudinal magnetic field strength of −74±44 G and a projected rotational velocity of 51 km/s. Tokovinin (2008) gives an estimated mass of 50 times the mass of the Sun for the primary, and 3.72 for the secondary. The tertiary member, component B, has 2.54 times the Sun's mass. (en)

  • 16 Sagittarii è una Stella multipla, presumibilmente binaria spettroscopica, dove la componente principale è una Gigante blu, forse facente parte di una Associazione OB, o più probabilmente, una primaria di tipo B.Presenta una magnitudine pari a 5,96 ed è situata nella costellazione del Sagittario. Tuttora è ancora sconosciuta sia la distanza dal nostro sistema solare, e inoltre sono molto incerti vari parametri orbitali e astrometrici, e quindi anche la magnitudine assoluta, che potrebbe darci indicazioni più certe sulla sua tipologia stellare. Si spera che la missione GAIA possa dirimere tali questioni. (it)
  • 16 Sagittarii, som är stjärnans Flamsteed-beteckning, är en trippelstjärna, belägen i den norra delen av stjärnbilden Skytten. Den har en kombinerad skenbar magnitud på 6,02 och är svagt synlig för blotta ögat även där ljusföroreningar ej förekommer. Den beräknas befinna sig på ett avstånd på ca 4 600 ljusår (ca 1 400 parsek) från solen och rör sig närmare solen med en heliocentrisk radialhastighet på ca -11 km/s. Den ingår i stjärnhopen Sagittarii OB7 och tillsammans med stjärnan 15 Sagittarii joniserar den en HII-region längs den västra kanten av molekylmolnet L291. (sv)
