Abstract
We analyze background fields along the bulge major axis away from the Galactic center by 2°.5, 13° and 31°. Our aim is to study the spatial distribution of different steiiar populations. A similar component of young disk main-sequence population is present in ali fields. The bulge component prevails in the innermost field, decreases for the 13° one, and is essentiaiiy absent in the 31° one. Evidence for a weak old metal-poor component is seen in the three fields. In the 13° field we detect a pe ...
We analyze background fields along the bulge major axis away from the Galactic center by 2°.5, 13° and 31°. Our aim is to study the spatial distribution of different steiiar populations. A similar component of young disk main-sequence population is present in ali fields. The bulge component prevails in the innermost field, decreases for the 13° one, and is essentiaiiy absent in the 31° one. Evidence for a weak old metal-poor component is seen in the three fields. In the 13° field we detect a peculiar new feature which could be interpreted as an intermediate-age component, and traces of this population in the 2°.5 field are also found. This might be an old disk component. ...
