    • Constraints on core-collapse supernova progenitors from explosion site integral field spectroscopy 

      Kuncarayakti, H.; Anderson, J. P.; Galbany, Lluis; Maeda, K.; Hamuy Wackenhut, Mario; Aldering, G.; Arimoto, N.; Doi, M.; Morokuma, T.; Usuda, T. (EDP Sciences, 2018-05-28)
      Context. Observationally, supernovae (SNe) are divided into subclasses according to their distinct characteristics. This diversity naturally reflects the diversity in the progenitor stars. It is not entirely clear, however, ...

C.; Weaver, B.; Wu, C. (2010-03)
      We present photometric and spectroscopic observations of SN 2007if, an overluminous (MV = -20.4), red (B -V = 0.16 at B-band maximum), slow-rising (trise = 24 days) type Ia supernova (SN Ia) in a very faint (Mg = -14.10) ...
