Scientific paper

SN 2006gy is the brightest supernovae known to mankind. Its classification and progenitor model remains a mystery as both type-Ia and type-II like properties were observed. Here we propose IRS observations with SL2, SL1 and LL2 in order to study the properties of the ejected envelope of this enigmatic event. Specifically, we will attempt to measure the amount of stable Nickel, thus constraining the progenitor mass. Furthermore, the proposed observations will allow to directly obtain the chemical composition using fine structure lines and to study the onset of dust condensation.
