  • ν Tucanae, Latinized as Nu Tucanae, is a solitary, variable star in the southern constellation of Tucana. This red-hued object is visible to the naked eye as a faint star with an apparent visual magnitude that fluctuates around +4.80. It is located approximately 290 light years from the Sun based on parallax, but is drifting closer with a radial velocity of −3 km/s. This object is an aging red giant with a stellar classification of M4 III, currently on the asymptotic giant branch. With the supply of hydrogen exhausted at its core, the star has cooled and expanded off the main sequence; at present it has 49 times the Sun's radius. It is classified as a slow irregular variable and its brightness varies from magnitude +4.75 to +4.93. Cyclical periods of 22.3, 24.4, 24.8, 25.1, 25.5, 33.8, 50.6, 80.1, 123.2, and 261.8 days have been reported for its variations. On average, the star is radiating around 400 times the luminosity of the Sun from its photosphere at an effective temperature of 3,674 K. (en)
  • Nu Tucanae (ν Tuc / ν Tucanae) é uma estrela na constelação de Tucana. Nu Tucanae é uma gigante vermelha de classe espectral M4III com uma magnitude aparente média de 4,91. É classificada como uma variável e sua luminosidade varia a magnitude de 4,75 a 4,93. (pt)
  • Ny Tucanae (ν Tuc, förkortat Ny Tuc, ν Tuc) som är stjärnans Bayerbeteckning, är en ensam stjärna belägen i den västra delen av stjärnbilden Tukanen. Den har en genomsnittlig skenbar magnitud på 4,80 och är synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 11,2 mas, beräknas den befinna sig på ett avstånd på ca 290 ljusår (ca 89 parsek) från solen. (sv)
