      Maeda, K.; Benetti, S.; Stritzinger, M.; Röpke, F. K.; Folatelli, Gastón; Sollerman, J.; Taubenberger, S.; Nomoto, K.; Leloudas, G.; Hamuy Wackenhut, Mario; Tanaka, M.; Mazzali, Paolo; Elias Rosa, N. (2010-07-01)
      Type Ia supernovae forman observationally uniform class of stellar explosions, in that more luminous objects have smaller declinerates 1. This one-parameter behaviour allows type Ia supernovae to be calibrated as ...
    • Evolving into a remnant: optical observations of SN 1978K at three decades 

      Kuncarayakti, Hanindyo; Maeda, Keiichi; Anderson, J. P.; Hamuy Wackenhut, Mario; Nomoto, K.; Galbany, Lluis; Doi, M. (Oxford Univ Press, 2016)
      We present new optical observations of the supernova SN 1978K, obtained in 2007 and 2014 with the Very Large Telescope. We discover that the supernova has not faded significantly, even more than three decades after its ...

J.; Ellison, S.; Frontera, F.; Fruchter, Andrew S.; Greiner, J.; Kawabata, K.; Ledoux, C.; Maeda, K.; Møller, P.; Nicastro, L.; Rol, E.; Starling, R. (NATURE PUBLISHING GROUP, 2006-08-31)
      Long-duration gamma-ray bursts (GRBs) are associated with type Ic supernovae(1) that are more luminous than average(2-5) and that eject material at very high velocities. Less-luminous supernovae were not hitherto known to ...
    • The peculiar type II supernova 1997D: A case for a very low Ni-56 mass 

      Turatto, M.; Mazzali, Paolo; Young, T. R.; Nomoto, K.; Iwamoto, K.; Benetti, S.; Cappellaro, E.; Danziger, I. J.; Mello, D. F. de; Phillips, M. M.; Suntzeff, Nicholas B.; Clocchiatti, A.; Piemonte, A.; Leibundgut, B.; Covarrubias, R.; Maza Sancho, José; Sollerman, J. (UNIV CHICAGO PRESS, 1998-05-10)
      SN 1997D in NGC 1536 is possibly the least luminous and energetic Type II supernova discovered to date. The entire light curve is subluminous, never reaching M-v = -14.65. The radioactive tail follows the Co-56 decay slope. ...
