About: HD 140913

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

HD 140913 is a star very much like our own Sun located in the northern constellation of Corona Borealis (The Northern Crown). It is too faint to be visible to the naked eye with an apparent visual magnitude of 8.07. The star is located at a distance of 158 light years from the Sun based on parallax. Prior to the discovery of a companion, this served as an IAU radial velocity standard, and it is receding from the Sun at a rate of +37 km/s. The space velocity components of this star are (U, V, W) = (-21.77, -14.42, 1.67).

dbo:abstract
  • HD 140913 ist ein etwa 156 Lichtjahre von der Erde entfernter Hauptreihenstern der Spektralklasse G0 im Sternbild Nördliche Krone. Er ist mit einer scheinbaren Helligkeit von 8,08 mag mit bloßem Auge auch unter optimalen Beobachtungsbedingungen nicht mehr zu sehen. Der Zentralstern wird von einem spektroskopischen Begleiter umrundet, bei dem es sich um einen kühlen Stern oder einen Braunen Zwerg handeln könnte. (de)
  • HD 140913 is a star very much like our own Sun located in the northern constellation of Corona Borealis (The Northern Crown). It is too faint to be visible to the naked eye with an apparent visual magnitude of 8.07. The star is located at a distance of 158 light years from the Sun based on parallax. Prior to the discovery of a companion, this served as an IAU radial velocity standard, and it is receding from the Sun at a rate of +37 km/s. The space velocity components of this star are (U, V, W) = (-21.77, -14.42, 1.67). This is a solar-type star with a stellar classification of G0V. It is an estimated seven billion years old and is spinning with a projected rotational velocity of 9.7 km/s. The star is about the same size as the Sun with 92% of the Sun's mass. It is radiating 1.2 times the Sun's luminosity from its photosphere at an effective temperature of 5,957 K. The detection of an orbiting companion, designated HD 140913 B, was announced in 1994. The minimum mass of this object is 43.2 times the mass of Jupiter, making it a brown dwarf candidate. Alternatively, it may be an under-mass helium white dwarf that has lost its envelope during a mass transfer. It orbits the host star about every 148 days with an eccentricity (ovalness) of ~0.57 and a semimajor axis of at least 0.55 AU. (en)
  • HD 140913 är en ensam stjärna belägen i den södra delen av stjärnbilden Norra kronan. Den har en skenbar magnitud av ca 6,78 och kräver åtminstone en handkikare för att kunna observeras. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 22,3 mas, beräknas den befinna sig på ett avstånd på ca 146 ljusår (ca 45 parsek) från solen. Den rör sig bort från solen med en heliocentrisk radialhastighet på ca 37 km/s. (sv)
