Title: Metallicity Gradients and Kinematic-Photometric Misalignment in S0 Galaxies in Sparse Environments

Abstract: S0 galaxies have long been associated with dense environments, quiescent star formation histories, and post-merger evolutionary phases. In the past 5 years, a relationship has been found between central metallicity and radial metallicity gradient in S0s located in supercluster environments. Additionally, several examples of kinematically-decoupled gas (both co-rotating and counter-rotating) have been found in S0s. Using SparsePak, we will obtain medium-resolution spectra of a small sample of isolated S0s with zero to mild inclination and reveal whether the [Z/H]-$\nabla$[Z/H] relationship and multiple kinematic components are traits exclusive to dense environments.
