About: Nu Eridani

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

Nu Eridani (ν Eri) is a star in the constellation Eridanus. It is visible to the naked eye with an apparent visual magnitude of 3.93. The distance to this star is roughly 520 light years, based upon an annual parallax shift of 0.00625 arcseconds. If the star were 33 ly (10 pc) from the Sun, it would be the brightest star in the night sky with an apparent magnitude of −2.84. (Currently, the brightest star is Sirius at magnitude −1.46.)

dbo:abstract
  • Nu Eridani (ν Eri) is a star in the constellation Eridanus. It is visible to the naked eye with an apparent visual magnitude of 3.93. The distance to this star is roughly 520 light years, based upon an annual parallax shift of 0.00625 arcseconds. If the star were 33 ly (10 pc) from the Sun, it would be the brightest star in the night sky with an apparent magnitude of −2.84. (Currently, the brightest star is Sirius at magnitude −1.46.) This is a B-type subgiant star with a stellar classification of B1.5 IV. It is a hybrid pulsator variable, lying as it does on the overlapping instability strips for Beta Cephei variables and slowly pulsating B-type stars. The star shows at least fourteen pulsations frequencies, with nine that also display radial velocity variations. It has about nine times the mass of the Sun and six times the Sun's radius. Nu Eridani shines with 7,943 times the solar luminosity from its outer atmosphere at an effective temperature of 22,000 K. (en)
  • Nu Eridani (ν Eri) est une étoile sous-géante de la constellation de l'Éridan. Sa magnitude apparente est de 3,93. C'est une étoile variable pulsante hybride, montrant à la fois les pulsations des étoiles de type B à pulsation lente et des variables de type Beta Cephei. Sa position sur le diagramme HR est en effet à cheval sur les deux bandes d'instabilité correspondant à ces deux types d'étoiles pulsantes. (fr)
  • Nu Eridani (ν Eridani, ν Eri) è una stella situata nella costellazione dell'Eridano. La sua magnitudine apparente è +3,92 e dista 674 anni luce dal sistema solare. (it)
  • Nu Eridani (48 Eridanus) é uma estrela na direção da constelação de Eridanus. Possui uma ascensão reta de 04h 36m 19.14s e uma declinação de −03° 21′ 08.8″. Sua magnitude aparente é igual a 3.93. Considerando sua distância de 586 anos-luz em relação à Terra, sua magnitude absoluta é igual a −2.34. Pertence à classe espectral B2III SB. É uma estrela variável β Cephei. (pt)
  • Ny Eridani, (ν Eridani, förkortat Ny Eri, ν Eri) som är stjärnans Bayerbeteckning, eller 48 Eridani, är en ensam stjärna belägen i den nordöstra delen av stjärnbilden Eridanus. Den har en genomsnittlig skenbar magnitud på 3,93 och är synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 6,3 mas, beräknas den befinna sig på ett avstånd på ca 520 ljusår (ca 160 parsek) från solen. (sv)
