Reclassification of SN 2020aekp (Gaia20fxk/ZTF21aaabwzx) as a Type Ia-CSM Supernova
Abstract
We reclassify SN 2020aekp as a Type Ia-CSM supernova. It was previously classified as a normal Type Ia based on a low-resolution spectrum taken around the time of its initial light curve maximum. The light curve subsequently declined and then plateaued, and strong CSM interaction features have developed in recent spectroscopy.
