About: Zeta Mensae

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

Zeta Mensae, Latinized from ζ Mensae, is a solitary, white-hued star in the southern constellation of Mensa. It is faintly visible to the naked eye, having an apparent visual magnitude of +5.64. Based upon an annual parallax shift of 8.2879 mas as seen from GAIA, it is located around 394 light years from the Sun. At that distance, the visual magnitude is diminished by an extinction factor of 0.088 due to interstellar dust. Eggen (1995) listed it as a proper motion candidate for membership in the IC 2391 supercluster.

  • Zeta Mensae, Latinized from ζ Mensae, is a solitary, white-hued star in the southern constellation of Mensa. It is faintly visible to the naked eye, having an apparent visual magnitude of +5.64. Based upon an annual parallax shift of 8.2879 mas as seen from GAIA, it is located around 394 light years from the Sun. At that distance, the visual magnitude is diminished by an extinction factor of 0.088 due to interstellar dust. Eggen (1995) listed it as a proper motion candidate for membership in the IC 2391 supercluster. The stellar classification of A5 III suggests this is an A-type giant star. It is spinning rapidly, showing a projected rotational velocity of 200 km/s, giving the star an oblate shape with an equatorial bulge that is an estimated 26% larger than the polar radius. The star is radiating about 69 times the Sun's luminosity from its photosphere at an effective temperature of around 7,555 K. It displays a faint infrared excess at a wavelength of 18μm, indicating that it is being orbited by a debris disk. (en)
  • Zeta Mensae (ζ Mensae, förkortat Zeta Men, ζ Men) som är stjärnans Bayerbeteckning, är en ensam stjärna belägen i den mellersta delen av stjärnbilden Taffelberget. Den har en skenbar magnitud på 5,64 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 på ca 414 ljusår (ca 127 parsek) från solen. På det beräknade avståndet minskar dess skenbara magnitud med 0,088 enheter genom skymning av interstellärt stoft. (sv)
  • Zeta Mensae (40 Mensae) é uma estrela na direção da constelação de Mensa. Possui uma ascensão reta de 06h 40m 02.91s e uma declinação de −80° 48′ 49.4″. Sua magnitude aparente é igual a 5.61. Considerando sua distância de 404 anos-luz em relação à Terra, sua magnitude absoluta é igual a 0.14. Pertence à classe espectral A5III. (pt)
