Long-term optical and near-infrared photometric evolution of SN 2019vxm, an interacting Type IIn supernova
Klára Lelkes, László Molnár, József Vinkó +12
The diversity of Type IIn supernovae is largely driven by the properties of the circumstellar material (CSM) they explode into. We examine the temporal evolution of SN 2019vxm, an…
