Supernova 2012A in NGC 3239.

ROY R. and CHAKRABORTI S.

Abstract (from CDS):

Rupak Roy, Aryabhatta Research Institute of Observational Sciences, Nainital; and Sayan Chakraborti, Tata Institute of Fundamental Research, Mumbai, on behalf of a larger collaboration, report that SN 2012A is a type-IIP supernova. Medium-resolution slit spectroscopy (range 350-750 nm) was acquired at the IUCAA Girawali Observatory on Jan. 10, showing broad H_alpha and H_beta features. With the help of the SNID code (Blondin and Tonry 2007, Ap.J. 666, 1024), they find the spectra to be most similar to that of the type-IIP supernova 2004et at age 1.9 days before maximum (age from explosion 14.2 days). The spectra are also similar to SN 2008in (also a type-IIP event; Chakraborti et al. 2008, CBET 1638) before maximum light.
