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.

NEOWISE对SNe II的中红外检测

在这里,我描述了在NEOWISE任务的附加图像中对184次超新星(SNe)的中红外探测。15个SNe以前没有发现持续时间超过一年的持久中红外检测结果。我发现了7个SNe,这些SNe以前没有过类似SN 2010jl的中红外演变。在一种IIb型(SN 2016gkg),IIP型(SN 2016X)和IIL型(SN 2016iot)周围也有很长的检测时间。SN 2018hna是一个不寻常的超新星,它显示了中红外的剧烈变化。SN 2018hna在发现后31天以无IR过量的瞬变开始,但在158天后变为具有强烈IR过量的瞬变。
