'grows radiantly' is the definition.
I can't tell whether this definition defines the answer.

'new star around the east' is the wordplay.
'new' indicates an anagram.
'around' is an insertion indicator.
'the east' becomes 'e' (synonyms).
'star' is an anagram of 'astr'.
'astr' enclosing 'e' is 'ASTER'.
