Aldulfin

Aldulfin is a modern star name adopted by the International Astronomical Union in the IAU-Catalog of Star Names (IAU-CSN). Its origin is Arabic. It is the name of HIP 101421 (ε Del, HR 7852) in constellation Del.

Etymology and History

Arabic scholarship adopted the Greek loanword "dulfim" or "dulfin" (with article: ad-dulfin or simplified adulfin) for the marine mammal. The star ε Del at the dorsal fin of the Ptolemaic (smaller than ancient Greek) figure was called Al Dhanab al Dulfim (the Dolphin's Tail) and as there are many stars named with the Arabic root for "tail", WGSN adopted only the last part of the name.
