| Abstract: |
Core-collapse supernovae (SNe) are believed to be the first significant source of dust in the Universe. We focus on the dust enrichment of a specific, luminous Lyman α emitter (LAE), Himiko, at z = 6.6. Based on the upper limit obtained by ALMA, we estimate a plausible upper limit to the dust mass produced by a single SN: <0.15–0.45 M☉. These upper limits are smaller than the dust mass deduced for SN 1987A and that predicted by dust condensation theories, implying that dust produced in SNe are likely to be subject to reverse shock destruction before being injected into the interstellar medium. |
