A lieutenant bearing one star (6)

I believe the answer is:

altair

'one star' is the definition.
(Altair is a star in the constellation of Aquila)

'a lieutenant bearing' is the wordplay.
'lieutenant' becomes 'lt' (abbreviation for lieutenant).
'bearing' becomes 'air' (both can mean an attitude or pose).
'a'+'lt'+'air'='ALTAIR'

(Other definitions for altair that I've seen before include "Heavenly body" , "Bright star; lariat (anag.)" , "A trial (anag) - star" , "Lariat (anag) - star in Aquila" , "Bright star in Aquila" .)

I've seen this clue in The Globe and Mail.
