Study of the outer galactic structure for 288°≤l≤310°, −7°≤b≤2°
The structure of the outer part of the Galaxy is studied, based upon 21-cm line observations of Hi in the region 288°≤l≤310°, −7°≤b≤2°. In this longitude range the galactic plane is strongly bend toward negative latitudes. The principal outer structure is a spiral arm which has a pitch angle of 10...

| Sumario: | The structure of the outer part of the Galaxy is studied, based upon 21-cm line observations of Hi in the region 288°≤l≤310°, −7°≤b≤2°.
In this longitude range the galactic plane is strongly bend toward negative latitudes.
The principal outer structure is a spiral arm which has a pitch angle of 10º and is formed by several concentrations differing in shape and size. There exists also a secondary concentration which could be a split from the previous structure.
Possible hypotheses about the origin of the later feature are discussed. |
