Intermediate-luminosity red transients: Spectrophotometric properties and connection to electron-capture supernova explosions

Y. -Z. Cai, A. Pastorello, M. Fraser +56

We present the spectroscopic and photometric study of five intermediate-luminosity red transients (ILRTs), namely AT 2010dn, AT 2012jc, AT 2013la, AT 2013lb, and AT 2018aes. They s…
