About: Theta Lupi

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

Theta Lupi, Latinized from θ Lupi, is a solitary star in the southern constellation of Lupus. It is visible to the naked eye with an apparent visual magnitude of 4.22. (The planetary nebula NGC 6072 lies 1.4° to the east-northeast.) Based upon an annual parallax shift of 7.87 mas as seen from Earth, it is located roughly 410 light years away from the Sun. Relative to its neighbors, this star has a peculiar velocity of 16.7±3.7 km/s. It is a member of the nearby Sco OB2 association.

  • Theta Lupi, Latinized from θ Lupi, is a solitary star in the southern constellation of Lupus. It is visible to the naked eye with an apparent visual magnitude of 4.22. (The planetary nebula NGC 6072 lies 1.4° to the east-northeast.) Based upon an annual parallax shift of 7.87 mas as seen from Earth, it is located roughly 410 light years away from the Sun. Relative to its neighbors, this star has a peculiar velocity of 16.7±3.7 km/s. It is a member of the nearby Sco OB2 association. This is a B-type main sequence star with a stellar classification of B2.5 Vn, where the 'n' suffix indicates nebulous lines due to spin. It is rotating rapidly with a projected rotational velocity of 331 km/s. This is giving the star an oblate shape with an equatorial bulge that is an estimated 15% larger than the polar radius. The star has an estimated 6.5 times the mass of the Sun and around 4.5 times the Sun's radius. With an age of just 24.6 million years, it is radiating 792 times the solar luminosity from its outer atmosphere at an effective temperature of 15,395 K. (en)
  • Theta Lupi (θ Lupi, θ Lup) è una stella singola situata nella costellazione del Lupo. La stella, così come altre stelle azzurre della costellazione del Lupo, è un membro dell'associazione stellare Scorpius-Centaurus, e più precisamente del sottogruppo Centauro superiore-Lupo, e la sua velocità peculiare di 16,7±3,7 km/s rispetto ai sistemi vicini fa ritenere che essa possa essere una stella fuggitiva. Situata a circa 410 anni luce dal sistema solare, la sua magnitudine apparente pari a +4,22 fa sì che questa stella sia visibile a occhio nudo nell'emisfero australe. (it)
  • Theta Lupi (157 Lupi) é uma estrela na direção da constelação de Lupus. Possui uma ascensão reta de 16h 06m 35.56s e uma declinação de −36° 48′ 08.0″. Sua magnitude aparente é igual a 4.22. Considerando sua distância de 411 anos-luz em relação à Terra, sua magnitude absoluta é igual a −1.28. Pertence à classe espectral B2.5Vn. (pt)

  • Theta Lupi (θ Lupi, förkortad Theta Lup, θ Lup), som är stjärnans Bayer-beteckning, är en ensam stjärna i östra delen av stjärnbilden Vargen. Den har en magnitud av 4,22 och är synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 7,9 mas, beräknas den befinna sig på ett avstånd av ca 410 ljusår (127 parsek) från solen. (sv)
