Styrian brat upset a heavenly couple? (6,4)
I believe the answer is:
binary star
'a heavenly couple?' is the definition.
The answer and definition can be both natural objects as well as being singular nouns.
Perhaps you can see an association between them that I don't see?
'styrian brat upset' is the wordplay.
I cannot really understand how this works, but
an anagram of 'styrian' is 'inaryst' which is located in the answer.
The remaining letters 'bar' is a valid word which might be clued in a way I don't understand.
This explanation may well be incorrect...
Can you help me to learn more?
(Another definition for binary star that I've seen is " Dual sun system".)
