Spectral classification

Umm...if it is K4III then it isn't a supergiant really...? These spectral type refs are pretty old....Cas Liber (talk · contribs) 13:50, 16 October 2017 (UTC)[reply]

2008 isn't so old for an MK catalogue. Simbad still shows K5Ib, but then it (allegedly) used to show M1.5Iab. I don't always understand Simbad's criteria for picking the preferred spectral type. Skiff gives a mix of K4III and K5-7Ib results. The luminosity is very high for a giant, but that really is old, I'll have a look for something newer.

Pronunciation

Suggestions for pronunciation from Barry Blake. I know it's OR, but since there's nothing published we don't have anything else to go on. The sound equivalents Blake suggests are all pretty standard for the era, so it's a common-sense interpretation even if you don't believe I contacted him. "u" is /a/ (/u/ would be "oo", as in 'Boorong') except when initial, when it's /ju/. An "r" may or may not be an /r/-type sound, since Oz is ar-dropping. "ite" was likely heard as [ait] (or [əit]), which would almost certainly be Wergaia /atj/. Initial /ŋ/ was generally omitted in transcription in this era. Wergaia stress is was on the first syllable, with secondary stress likely on the third. (See Reid's Wergaia Community Grammar and Dictionary.) So, assuming no initial /ŋ/, anglicization would be YEW-nə(r)-gun-yte (full vowel in 'gun'), though YEW-nə(r)-GUN-yte would also be close. Blake suggests an initial /ŋ/ for the Wotjobaluk form "Urnugunite", in which case the Boorong form should have an initial /ŋ/ too, but that makes no difference for the anglicized IAU form. — kwami (talk) 19:55, 23 April 2019 (UTC)[reply]
