Abstract
The evolution of a superbubble driven by sequential explosions of supernovae in an OB association is studied. Particular attention is given to the effect of the plane-stratified gas distribution in the direction perpendicular to the galactic disk. It is shown that the superbubble asymmetrically expands with respect to the parallel and perpendicular directions to the disk. In the case that the density on the disk plane, n0, is about 1/cu cm, it is found that the cooled shell surrounds the hot cavity like an egg shape. On the other hand, in a low-density disk with n0 of about 0.1/cu cm, a cooled wall is formed only on the disk plane side of the bubble and the hot gas flows up to the halo region. This corresponds to the H I worms pointed out by Heiles (1984). It is shown that the hot gas which is pushed up maintains the galactic hot gaseous halo.
