Mid-Infrared Detections of SNe II with NEOWISE.

THEVENOT M.

Abstract (from CDS):

Here I describe 184 mid-infrared detections of supernovae (SNe) in co-added images of the NEOWISE mission. 15 of the SNe had previously unknown long-lasting mid-IR detections with durations of more than a year. I find 7 SNe which have previously unknown SN 2010jl-like mid-infrared evolution. There are also long detections around one type IIb (SN 2016gkg), type IIP (SN 2016X) and type IIL (SN 2016iot). An unusual supernova is SN 2018hna, which shows a drastic color-change in mid-infrared. SN 2018hna begins as a transient with no IR-excess 31 days after the discovery, but changes 158 days later into a transient with strong IR-excess.
