Shocked Interstellar Clouds and Dust Grain Destruction in the LMC Supernova Remnant N132D

Dopita, Michael; Vogt, Frédéric P.A.; Sutherland, Ralph; Seitenzahl, Ivo R; Ruiter, Ashley J; Ghavamian, Parviz


From integral field data we extract the optical spectra of 20 shocked clouds in the supernova remnant N132D in the Large Magellanic Cloud (LMC). Using self-consistent shock modeling, we derive the shock velocity, pre-shock cloud density, and shock ram pressure in these clouds. We show that the [Fe x] and [Fe xiv] emission arises in faster, partially radiative shocks moving through the lower-density gas near the periphery of the clouds. In these shocks dust has been effectively destroyed, while...[Show more]
