The origin and evolution of the normal Type Ia SN 2018aoz with infant-phase reddening and excess emission

Yuan Qi Ni, Dae-Sik Moon, Maria R. Drout +40

SN~2018aoz is a Type Ia SN with a -band plateau and excess emission in the infant-phase light curves 1 day after first light, evidencing an over-density of surface ir…
