  • ι Lyrae, Latinised as Iota Lyrae, is a binary star in the northern constellation of Lyra. It is visible to the naked eye as a dim, blue-white hued star with an apparent visual magnitude that fluctuates around 5.22. This object is located approximately 950 light years distant from the Sun based on parallax, but is drifting nearer with a radial velocity of −26 km/s. This is a wide binary system with a computed orbital period of 217 years and an eccentricity of 0.6. The primary component has a stellar classification of B6IV, matching a B-type subgiant star. It is a Be star, displaying emission lines in its spectrum, and is spinning rapidly with a projected rotational velocity of 224 km/s. The star ranges in brightness from magnitude 5.20 down to 5.27. It has five times the mass of the Sun and is radiating 1,349 times the Sun's luminosity from its photosphere at an effective temperature of 13,428 K. (en)
  • Iota Lyrae (18 Lyrae) é uma estrela na direção da constelação de Lyra. Possui uma ascensão reta de 19h 07m 18.13s e uma declinação de +36° 06′ 00.6″. Sua magnitude aparente é igual a 5.25. Considerando sua distância de 832 anos-luz em relação à Terra, sua magnitude absoluta é igual a −1.78. Pertence à classe espectral B6IV. É uma estrela Be. (pt)
  • Jota Lyrae (ι Lyrae, förkortat Jota Lyr, ι Lyr) som är stjärnans Bayerbeteckning, är en dubbelstjärna belägen i den mellersta delen av stjärnbilden Lyran. Den har en skenbar magnitud på +5,2 - 5,27 och är synlig för blotta ögat där ljusföroreningar ej förekommer. Baserat på parallaxmätning inom Hipparcosuppdraget på ca 3,6 mas, beräknas den befinna sig på ett avstånd av ca 900 ljusår (270 parsek) från solen. (sv)
