Jirradella in a Wardaman star map (CC BY Cairns and Harney 2003)[1].

Jirradella, rainbow signs, is a name for the star β TrA (in Triangulum Australe) from the Australian Wardaman people.

Etymology and History

The Wardaman name "Jirradella" means "rainbow's sign" (Cairns & Harney, 2003,[1] p.201).

Mythology

IAU Working Group on Star Names

The name was discussed by the IAU WGSN in 2018, however no action was taken in adopting it for a star. The name may be revisited at a future WGSN meeting.

Beta Trianguli Australis lacks a proper name in SIMBAD, the wikipedia, Bright Star Catalog (4th, 5th editions), and Kunitzsch & Smart (2006). see also http://stars.astro.illinois.edu/sow/betatra.html

β TrA (GJ 601A, HD 141891, HR 5897, HIP 77952) is a bright (apparent V magnitude 2.85) and nearby (12.4 parsecs) star of spectral type F1V. Although it appears in the Washington Double Star catalog (WDS J15551-6326A, LDS 542), the "B" component (WDS J15551-6326B, GJ 601B, LTT 6333) is an unrelated background star at roughly 280 parsecs distance. Thus far, β TrA appears to be single.
