Variable Sodium Absorption in a Low-extinction Type Ia Supernova (2009)
Simon, Joshua D., Gal-Yam, Avishay, Gnat, Orly, Quimby, Robert M., Ganeshalingam, Mohan, Silverman, Jeffrey M., ...
Recent observations have revealed that some Type Ia supernovae exhibit narrow, time-variable Na I D absorption features. The origin of the absorbing material is controversial, but it may suggest the...

The only supernovae (SNe) to have shown early gamma-ray or X-ray emission thus far are overenergetic, broad-lined Type Ic SNe (Hypernovae - HNe). Recently, SN 2008D shows several novel features: (i)...

Supernovae connected with long-duration gamma-ray bursts (GRBs) are hyper-energetic explosion resulting from the collapse of very massive stars (about 40Mo, where Mo is the mass of the Sun) stripped...
