υ⁶ Eridani (g Eridani)
υ⁷ Eridani (h Eridani)

This series of stars bore the traditional proper names Theemim (also Theemin) and Beemin (also Beemim).^[1]^[2] In 2016, the International Astronomical Union organized a Working Group on Star Names (WGSN)^[3] to catalog and standardize proper names for stars. The WGSN approved the names Theemin for υ² Eridani on 1 February 2017 and Beemim for υ³ Eridani on 30 June 2017; both are now included in the List of IAU-approved Star Names.^[4]
