Description = [[Census: 61 OB associations. DU Version 2.4. <br> OB associations
|
|
are young groups of stars that were formed within a giant molecular cloud, but
|
|
have dispersed after the original gas and dust from the cloud was blown away
|
|
by the star's radiation pressure. Although an association's stars are no
|
|
longer gravitationally bound to one another, they share a common motion in
|
|
space because they were formed from the same cloud. This allows astronomers to
|
|
easily determine OB association membership stars. These objects are color
|
|
coded by their spiral arm membership. Blue associations trace the Sagittarius
|
|
Arm. Purple associations are in the local Orion Spur. Orange associations are
|
|
in the Perseus Arm (Description from URL) <br><br> Data Reference: New List of
|
|
OB Associations (Melnik+)]],
