Title: HexPak Survey Emission Line Properties of S0/a Central Molecular Zones

Abstract: This is a short version of a proposal in response to the request for secondary WIYN proposals. A subset of S0 galaxies have compact obscured nuclei, regions with sizes of $leq$ 100~pc that produce FIR luminosities of $sim 10^{10}$ to $10^{11}$~L$_{odot}$ and contain extremely dense molecular gas. Despite their supplies of gas with great potential for star formation, it is not clear if they host nuclear starbursts, but several systems show post burst spectra. The recently detected neutron star merger event is also in an S0 galaxy with a possible postburst spectrum. This is a quick proposal to continue our Hexpak study of the ionized gas kinematics and densities, primarily in a sample of S0/a galaxies located near the Virgo galaxy cluster in the Local Supercluster (D $leq approx$ 30~Mpc). In this study we will focus on evidence for prerocessing (i.e. rapid late phase evolution) via studies of the central regions of S0/a systems in and around Virgo and other galaxy clusters.
