IR and sub-mm fluxes of SN1987A revisited: when moderate dust masses suffice
Abstract
We model the fluxes in the infrared and submillimeter domain using the dust chemical composition and mass derived from the physico-chemical model of a Type II-P supernova ejecta with stellar progenitor of 19 M ⊙. Our results highlight that the dust mass predicted to rise over time in our chemical models from 10-2 to 10-1 M ⊙ satisfactorily reproduce the infrared and sub millimeter fluxes. They confirm that type II-P SNe are efficient but moderate dust makers in galaxies.
