Jets and outflows must be produced directly from accretion disks and in-flows, especially when the central gravitating objects are compact, such as neutron stars and black holes, and themselves arenotmass losing. Here, we review the formation of jets from advective inflows. We show that the centrifugal pressure supported boundary layer (CENBOL) of the black holes may play crucial role in producing outflows. CENBOL is not present in Keplerian disks. Thus energetic jet formation is directly connected to sub-Keplerian flows close to compact objects. ©2001 American Institute of Physics.
