41 Arietis (abbreviated 41 Ari) is a triple star system in the northern constellation of Aries. With an apparent visual magnitude of 3.63, this system is readily visible to the naked eye. It has an annual parallax shift of 19.69 mas, which indicates it is at a distance of {{Convert|166|ly|pc|abbr=off|lk=on}} from the Sun.

The system consists of a binary pair, designated 41 Arietis A, together with a third companion star, 41 Arietis D. (41 Arietis B and C form optical pairs with A, but are not physically related.{{cite web | url=http://ad.usno.navy.mil/wds/ | title=Washington Double Star Catalog | publisher=United States Naval Observatory | access-date=2 January 2018 | archive-url=https://web.archive.org/web/20110214155533/http://ad.usno.navy.mil/wds/ | archive-date=2011-02-14 | url-status=dead }}) The components of A are themselves designated 41 Arietis Aa (formally named Bharani {{IPAc-en|ˈ|b|ær|ə|n|i}}){{cite web | url=https://www.iau.org/public/themes/naming_stars/ | title=Naming Stars |publisher=IAU.org |access-date=16 December 2017}} and Ab.

Nomenclature

41 Arietis is the system's Flamsteed designation. It does not possess a Greek-letter Bayer designation, since this system was once part of the now-obsolete constellation Musca Borealis, but is sometimes designated c Arietis. 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 (WMC) for multiple star systems, and adopted by the International Astronomical Union (IAU).{{cite arXiv |title=On the naming convention used for multiple star systems and extrasolar planets |date=2010 |eprint=1012.0707 |class=astro-ph.SR |last1= Hessman |first1=F.

Nicolas-Louis de Lacaille called the star Līliī Austrīnā ({{IPAc-en|ɔː|ˈ|s|t|r|aɪ|n|ə}}) 'southern of Lilium' (in Latin) in 1757,{{cite book |first=Nicolas-Louis |last=de Lacaille |title=Astronomiae fundamenta novissimis solis et stellarum observationibus stabilita, Lutetiae in Collegio mazarineo et in Africa ad caput Bonae Spei peractis a Nicolao Ludovico de La Caille |url=https://books.google.com/books?id=LXm0RAf6fk0C |publisher=J.-J.-St. Collombat |date=1757 |pages=227, 233}}{{cite book |first=Francis |last=Bailey |title=La Caille's Catalogue of 398 principal Stars, Memoirs of the Royal Astronomical Society, Vol 5 |url=https://books.google.com/books?id=1l9dAAAAcAAJ |publisher=Priestley and Weale |date=1833 |pages=110, 121}} as a star of the now-defunct constellation of Lilium (the Lily). To him 39 Arietis was Līliī Boreā, 'northern of Lilium'.

In Hindu astronomy, Bharani (भरणी bharaṇī, {{IPA|sa|ˈbʱɐɽɐɳiː}}) 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 (WGSN){{cite web | url=https://www.iau.org/science/scientific_bodies/working_groups/280/ | title=IAU Working Group on Star Names (WGSN)|access-date=22 May 2016}} to catalog and standardize proper names for stars. The WGSN decided to attribute proper names to individual stars rather than entire multiple systems.{{cite web | url=https://www.iau.org/static/science/scientific_bodies/working_groups/280/wg-starnames-triennial-report-2015-2018.pdf | page=5 | title=WG Triennial Report (2015-2018) - Star Names |access-date=2018-07-14}} 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, {{lang|zh|胃宿}} ({{lang|zh-Latn|Wèi Su}}), meaning Stomach (asterism), refers to an asterism consisting of 41, 35 and 39 Arietis.{{in lang|zh}} 中國星座神話, written by 陳久金. Published by 台灣書房出版有限公司, 2005, {{ISBN|978-986-7332-25-7}}. Consequently, the Chinese name for 41 Arietis itself is {{lang|zh|胃宿三}} ({{lang|zh-Latn|Wèi Su sān}}, {{langx|en|the Third Star of Stomach}}.){{in lang|zh}} 白羊座

In Avestan, the star was known as Upa-paoiri, and it was associated with one of the yazatas.[http://www.avesta.org/angels.html ANGELS:Zoroastrian]

Properties

The primary component is a B-type main sequence star with a stellar classification of B8 Vn. The suffix 'n' indicates 'nebulous' absorption lines in the star's spectrum caused by the Doppler effect of rapid rotation. It has a projected rotational velocity of 175 km/s. This is creating an equatorial bulge that is 12% larger than the star's polar radius. It is a candidate member of the AB Doradus moving group and has an orbiting companion at an angular separation of 0.3 arcseconds.
