HE 1327-2326, discovered in 2005 by Anna Frebel and collaborators, was the star with the lowest known iron abundance until SMSS J031300.36−670839.3 was discovered. The star is a member of Population II stars, with a solar-standardised iron to hydrogen index [Fe/H], or metallicity, of −5.4±0.2. The scale being logarithmic, this number indicates that its iron content is about 1/250000 that of the Earth's sun. However, it has a carbon abundance of roughly one-tenth solar ([C/H] = −1.0), and it is not known how these two abundances can have been produced/exist simultaneously. Discovered by the Hamburg/ESO survey for metal-poor stars, it was probably formed during an age of the universe when the metal content was much lower. It has been speculated that this star is part of the second generation

  • HE 1327-2326 هي مجرة تتبع كوكبة الشجاع. اكتشفها أنا فريبيل في 2005. (ar)
  • HE 1327-2326は、太陽系から見てうみへび座の方向約3,470光年の距離にある恒星である。2005年に発見された時点で最も金属量の少ない恒星であった。太陽より軽く、年齢は130億年と推定されている。これは既知の恒星の中では最も古いものの1つである。 (ja)
  • HE 1327-2326은 현재까지 발견된 별 중에서 가장 중원소 함량(태양의 1/200,000)이 낮은 별이다. 이 별은 항성종족 II에 속하며, 그 수치는 -5.4 ~ -5.6이다. 이 별의 중원소함량 수치는 지구의 태양의 30만 분의 1에 불과하다. 그러나 탄소의 수치는 [C/H] = -1.0으로, 아직 확실하게 밝혀지지는 않았다. 이 별은 유럽 남방 천문대가 발견하였으며, 항성종족 III의 별이 죽고 나서 남은 곳에서 바로 생겨났을 것으로 추측된다. 나이는 136억 년 정도로 추정된다. (ko)
  • HE1327-2326在2005年被和共同研究者發現，是迄今為止所知鐵豐度最低的恆星。這顆恆星是第二族恆星，它的鐵對氫的比率([Fe/H])，或金屬量是-5.6。這個數值表示擁有地球的太陽，其鐵含量是它的300,000倍。但是，它的碳豐度大約是太陽的十分之一，[C/H]=-1.0，而我們不知道這兩種不同的豐度是如何同時形成的。經由漢堡/歐洲太空總署的貧金屬星調查發現，它可能是在金屬含量還非常低的宇宙早期就形成的。推測這顆第二星族的恆星是在被汙染的原始的第三星族恆星誕生的氣體雲內形成的。 (zh)
  • HE1327-2326 ist ein Kohlenstoffstern im Sternbild Wasserschlange. Er war bis zur Entdeckung von SMSS J031300.36-670839.3 im Jahre 2014 der Stern mit dem geringsten bekannten Eisenanteil. HE1327-2326 wurde 2005 von der Astronomin Anna Frebel und ihrem Team im Rahmen der Hamburg/ESO-Durchmusterung für metallarme Sterne am Siding-Spring-Observatorium entdeckt. HE1327-2326 gehört zur 2. Population und ist zu einer Zeit entstanden, als das Universum noch viel weniger Metalle (hier: Elemente außer Wasserstoff und Helium) enthielt als heute. (de)

  • HE 1327-2326 (SPM3.2 4266486) es una estrella en la constelación de Hidra de magnitud aparente +13,15.​ Está a una distancia máxima de 4000 años luz del Sistema Solar.​ Descubierta en 2005, es la estrella conocida con menor abundancia relativa de hierro. HE 1327-2326 es una estrella subgigante o de la secuencia principal,​ catalogada en la base de datos SIMBAD como estrella de carbono.​ La presencia de líneas CH en su espectro​ son características de una estrella CH.

  • HE 1327-2326 est une étoile de magnitude 13,5 située dans la constellation de l'Hydre femelle. Découverte en 2005, son analyse chimique a montré que sa métallicité (mesurée par le rapport [Fe/H]) est de −5,6, soit une abondance en métaux plus de 200 000 fois inférieure à celle du Soleil. En 2019, une étude montre que sa teneur en zinc est anormalement élevée avec un rapport [Zn/Fe] de 0,8 ± 0,25, c'est-à-dire environ 6,3 fois plus que dans le Soleil. Cette observation surprenante pourrait être le signe de l'existence de supernovas à symétrie non sphérique parmi les étoiles de population III. (fr)
  • HE 1327-2326 è una stella di sequenza principale o subgigante situata nella costellazione dell'Idra; dista circa 4000 anni luce dalla Terra. È una delle stelle con minori quantità di ferro conosciute: [Fe/H] = −5,4 ± 0,2, cioè 250.000 volte inferiore a quella solare. Tuttavia presenta grandi abbondanze di carbonio e azoto rispetto a quella di ferro. Per esempio, [C/H] = −1,4, ossia possiede una quantità di carbonio che è il 3% di quella solare. Ancora più abbondante è l'azoto: [C/N] = −1,1, ossia l'8% di quello solare. (it)
