A Tale of Three Dust Populations: Variable $R_{\rm{V}}$ and Extreme Polarization Along Sightlines Toward $\zeta$ Ophiuchi

Dust permeates the interstellar medium, reddening and polarizing background starlight, but dust properties vary with local environment. In order to characterize dust in a highly irradiated diffuse cloud, we measure the reddening and optical polarization towards 27 stars surrounding the mid-latitude...
