Description
We present calculations that account for the infall of matter onto the
heart of a starburst, a condition thought indispensable for causing the
large accumulation of matter and the large detected rates of star
formation. We center our attention on the rapid evolution of the remnant
generated by the collective action of strong stellar winds and
supernovae and particularly on its rapid approach toward a steady state,
or pressure-confined, solution. Two different stationary solutions may
result depending on the relative thickness of the infalling disk
compared with the distance along the galaxy plane at which the reverse,
or inner, shock acquires its stationary location. In both cases the
infalling disk matter experiences a giant splash after crossing the
outer shock to be ejected into lower pressure zones at large distances
away from the heart of the starburst. Also, in both cases the giant disk
matter splash ends up confining the central wind into a biconical flow
with a stationary, narrow (~ a few hundred pc) central waist. The
observational implications of both stationary solutions are discussed.
