Nomenclature
41 Arietis is the system's Flamsteed designation. Bayer did not assign a designation to this star, but Bode introduced the designation c Arietis. Bode considered the star part of the asterism Musca Borealis within Aries – he called the entire constellation Aries et Musca. The designations of the two constituents as 41 Arietis A and D, and those of A's components - 41 Arietis Aa and Ab - derive from the convention used by the Washington Multiplicity Catalog for multiple star systems, and adopted by the International Astronomical Union.Nicolas-Louis de Lacaille called the star Līliī Austrīnā 'southern of Lilium' in 1757, as a star of the now-defunct constellation of Lilium. To him 39 Arietis was Līliī Boreā, 'northern of Lilium'.
In Hindu astronomy, Bharani is the second nakshatra, or lunar mansion corresponding to 35, 39 and 41 Arietis. In 2016, the IAU organized a Working Group on Star Names to catalog and standardize proper names for stars. The WGSN decided to attribute proper names to individual stars rather than entire multiple systems. It approved the name Bharani for the component 41 Arietis Aa on 30 June 2017 and it is now so included in the List of IAU-approved Star Names.
In Chinese, 胃宿, meaning Stomach , refers to an asterism consisting of 41, 35 and 39 Arietis. Consequently, the Chinese name for 41 Arietis itself is 胃宿三
In Avestan, the star was known as Upa-paoiri, and it was associated with one of the yazatas.
