Modern name for Delta Eridani = HR 1136; astrophysical importance: one of the first (rare) exemplars of “subgiants” recognized.
Etymology and History
The star was called "Rana Secunda" in Piazzi's Palermo Catalog (1814; Praecipuarum Stellarum Inerrantium Positiones Mediae Ineunte Saeculo XIX. Ex Observationibus Habitis In Specula Panormitana Ab anno 1792 ad annum 1813), however this appears to have been shortened to "Rana" in later works.
The name appears to have been misappropriated by Piazzi or his team:
- Rana Secunda <- “2nd frog” <- ضفدع الثاني aḍ-ḍifdaʿ aṯ-ṯānī – attributed to Beta Ceti “Diphda” (where 1st frog was Fomalhaut) (Hyde’s 1665 translation of Ulugh Beg, Leybourn 1694, Knobel 1895).
- Strangely it is obvious from Hyde’s translation of Ulugh Beg’s text that the Latinized Rana Secunda is referring to a star in the tail of Cetus.
Despite the misappropriation, the name propagated. Later references, all as “Rana” for del Eri:
