Abstract:
We want to make a large-scale study of the morphology, kinematics, and
origin of the HI, which surrounds the Sco-Cen association.
We combine our high-sensitivity southern HI survey with the
Leiden/Dwingeloo Survey, considering l=240°-400°, b=-60° to
+60°, and radial velocities of V=-41.8 to +40.8km/s. We point out
the main HI branches surrounding the association and derive their
kinematics. Kinematical HI-maps were compared with spatial maps of
interstellar (IS) NaI from the literature. Upper limits for distances
d were derived from optical IS absorption components from the
literature. Models of expanding spherical HI shells were fitted
around each stellar subgroup.
Description:
In this paper we are using our new high-sensitivity southern 21-cm line
survey (see Arnal et al., 2000, ASP Conf. Ser., 218, 401), combined
with the Leiden/Dwingeloo Survey of Galactic Neutral Hydrogen
(Hartmann & Burton, 1997, Atlas of Galactic Neutral Hydrogen
(Cambridge Univ. Press)).
