Tepiamenit, Predecessor of the Pole, is a modern star name adopted by the International Astronomical Union in the IAU-Catalog of Star Names (IAU-CSN). Its origin is ancient Egyptian. It is the name of the star τ Boo (HIP 67275, HR 5185) in constellation Bootes.
Concordance, Etymology, History
Tepiamenit (spelled tpy` mnỉt6) as a term is mentioned in the Ramesside Star Clocks (RSC) that are found in tombs of some Ramses kings.
"Menit" is the Pole or Mooring post and refers to the Celestial and Ecliptic Poles. In depictions it is drawn as a triangular device held at its position by Reret, the Hippopotamus. Reret and Menit together form a super-constellation of high cultural importance in the ancient Egyptian sky.
As there has been no pole star in the 2nd millennium BCE, the "pole" was in a dark area and Belmonte (2003)[2] identifies its right ascension with Alkaid (η UMa) in Ursa Major.
Between Tepiamenit, Predecessor of the Pole, and the Pole itself, there is Muphrid (η Boo). In the epoch around 1250 BCE, Muphrid (11h 14m) and Alkaid (11h 18m) have almost the same right ascension. Therefore, it appears consequent to search Tepiamenit also at roughly the same right ascension and in the vicinity of Muphrid. Tepiamenit as a term is directly written in hieroglyphs in some RSCs, but without a number, close to the neighbouring right ascension (the one given for Muphrid). So, it has to be located in the area of Bootes (or Ursa Major).
Belmonte (2003) identifies τ Boo, which is separated from Muphrid by only 2°.
Mythology
IAU Working Group on Star Names
The name was proposed as a candidate proper name for a naked eye star in the vicinity of Muphrid that would preserve the heritage of this ancient Egyptian asterism. The WGSN adopted the name Tepiamenit for the star τ Bootis and added it to the IAU-CSN on April 16, 2026.
The name was assigned specifically to the bright (V=4.50 magnitude) F7V-type star τ Boo A (HD 120136, GJ 527A, HR 5185, HIP 67275) , which is in a binary system with a faint red dwarf companion τ Boo B. Orbiting τ Boo A / Tepiamenit on a very close-in 3.3-day orbital period orbit is the famous exoplanet τ Boo Ab, which was one of the first 'hot Jupiter' type exoplanets discovered (by Paul Butler and collaborators 1997). τ Boo Ab and its host star were one of the initial exoplanetary systems selected for public naming in the first IAU NameExoWorlds (2015) campaign, however the top vote-getting selection was disqualified, and the system went unnamed (Montmerle 2019).
