The Stellar Populations that Heat the Dust in AndromedaMaria Kapala

K. Sandstrom & B. Groves

(1) strong correlation: stellar attenuated UV & dust surface density (2) attenuated UV emission is generated mostly (~88%) by B3 and earlier type stars, ~26% from O stars

(3) attenuated NUV correlates well with dust reemission in IR
