Star system description: Albireo
Albireo is the well-known visual pair AB (34.3″). Its component structure also includes closer measured pairs; AB is the pair shown in the miniature.
Pair AB (34.3″; magnitudes 3.19 and 4.68) is the binocular candidate in the catalog model. Actual resolution depends on magnification and stability.
The diagram uses the latest WDS measurements; north is up and east is right. Measurements may be from different years. Unconnected groups are arranged separately; close pairs may merge, and pairs without reliable geometry are omitted.
