Continued Observations of Interacting and Dust Producing CCSNe

Determing whether core collapse supernovae (CCSNe) are significant dust producers and the source of massive amounts of dust seen in high redshift galaxies is still an important unanswered question in astronomy. Recently, over 0.1 Msun of cold dust has been found in SN 1987A and the Crab Nebula which may help prove this is the case. We propose to continue GMOS observations of two bright, interacting CCSNe 2010jl and 2011ja to look for signs of condensing dust as well as to help characterise the circumstellar medium created by mass loss from the progenitor star. These continued observations will help form a baseline which is essential for disentangling newly formed ejecta dust from pre-existing dust surrounding the SN.
