Lilii Borea is a modern star name adopted by the International Astronomical Union in the IAU-Catalog of Star Names (IAU-CSN). Its origin is Latin. It is the name of the star 39 Arietis in constellation Aries.

Etymology and History

Ignace-Gaston Pardies introduced a new (now obsolete) constellation, Lilium, the fleur-de-lis of France, in 1674.[1][2][3] He had reused four stars in the north of Aries, which were unnamed in Antiquity and subject to various namings in the Early Modern Ages. The individual stars of the Lily were unnamed.

In the Almagest, it is listed as "The 4 stars over the rump [of the Ram]", outside the constellation image.

Mythology

The Lily was an emblem of France: the "Fleur-de-lis" (Unicode U+269C ⚜) is a heraldic symbol. In particular, in the time of Louis XIV this symbol was dedicated to the French king as the country's representative.

IAU Working Group on Star Names

In 2017 the IAU WGSN adopted Lacaille’s name Lilii Borea for 39 Arietis, a 4.52 mag-star HR 824 (SIMBAD). They gave 41 Arietis the name Bharani after the second nakshatra (lunar mansion) in Hindu astronomy, consisting of 35, 39, and 41 Arietis. The name was adopted by the IAU WGSN on 2017/09/05.

In 2023/ 24 the IAU WGSN discussed the parallel name. As the identification of Lilii Austrina with 41 Arietis is without any doubt due to the given coordinates, and this star already has a name given by the IAU already (Bharani (भरणी)), WGSN refrains from applying "Lilii Austrina".
