Skyculture "Ruanui sky : Tahitit and Society islands"

[ThibaudGS]

Description

A new skyculture was added "Ruanui sky : Tahitit and Society islands".
This skyculture contains stars and constellations used in traditional polynesian astronomy in Society Islands (Tahiti, Bora bora...).
The main book reference we used was "Ancient Tahiti", therefore these stars are mainly the stars taught by Ruanui, an old lady from Bora bora whose knowledge was translated in the Book "Ancient Tahiti" by Teuira Henry.

This skyculture was missing, and our working group is proud to add this relevant addition to the Stellarium software, so that the polynesian population, but also a larger audience, can access this traditional knowledge.

The working group was composed of tahitian experts in polynesian astronomy (Christine Briant, Libor Prokop, Regis Plichart) and cultural tahitian associations ("Fa'afaite i te ao maohi", "Te Fare Hiroa no Vavau").

Since version 25.1 we have a new format for storing the data of sky cultures and conversion tool from old format to the new one.

At the moment I have a few questions:

• Having the people of Tahiti and Society islands specific writing system or it uses a latin alphabet?
• Could you share an English names for planets also?
• Could you share an English names for stars also?
• What meaning names like "A5/T5" or "A2b" - is it really names or just some designations?

[ThibaudGS]

Hello Alex-w,

Thank you for your reply !

Where can I find the conversion tool ?

Here are the anwsers :

• The people of Tahiti use a latin alphabet with some special letters like "ā" and the use of apostrophe
• I could share a translation for the planet and star names in english, but where do I put it ? Is it in a new file ? I choose the Hawaian skyculture as an example, and I can't find the translations for the stars and planets.
• "A5/T5" and "A2b" are some designations used to distinguish some stars that may have different names depending on the reference used.

Thank you for your help !

Please see User Guide chapter 9.

I updated the file for the planets names, using the user guide. For instance Saturn look now like this :
Saturn "Fetūtea" _("Pale star")

But I fail to find a way to do the same with stars. According to the user guide, the code for a star should look like this :
102098|_("Ta'urua-i-te-ha'apāra'a-manu") 1

Where can I put the english translation for the native name of a star ? I agree it would be very interesting as the translation is often a complete sentence.

Thanks a lot for your help !

Please update to current version 25.1 and then use the User Guide that comes with version 25.1, chapter 9, to find all instructions, and take skycultures that come with 25.1 for examples. Convert your work with the converter that comes with version 25.1, then continue work on the converted result. Note that 25.1 does not show all cultural names on screen yet, but 25.2 (scheduled for June) will.

Thank you qzotti, i'm working on it

[sushoff]

better examples are the Siberian, Chinese and Greek (Almagest) - I think, they are the most complete (in terms of foreign characters, translations etc.)

Good luck!
