I believe this clue is a double definition.

'arcturus' is the first definition.
(I've seen this in another clue)

'altair or antares' is the second definition.

(Other definitions for star that I've seen before include "Famous person" , "Famous entertainer" , "For example, Marilyn Monroe" , "Astronomer - dreamer" , "Top celebrity" .)

I've seen this clue in The Wall Street Journal.
