Expanded Sample of Small Magellanic Cloud Ultraviolet Dust Extinction Curves: Correlations between the 2175 A bump, q_pah, UV extinction shape, and N(HI)/A(V)

Karl D. Gordon, E. L. Fitzpatrick, Derck Massa +7

The Small Magellanic Cloud (SMC) shows a large variation in ultraviolet (UV) dust extinction curves, ranging from Milky Way-like (MW) to significantly steeper curves with no detect…
