Scientific paper

We review the properties of supernovae (SNe) as a function of the progenitor's mass M. (1) 8-10 Msolar stars are super-AGB stars and resultant electron capture SNe may be Faint supernovae like Type IIn SN 2008S. (2) 10-13 Msolar stars undergo Fe-core collapse to form neutron stars (NSs) and Faint supernovae. (3) 13 Msolar-MBN stars undergo Fe-core collapse to form NSs and normal core-collapse supernovae. (4) MBN-90 Msolar stars undergo Fe-core collapse to form Black Holes. Resultant supernovae are bifurcate into Hypernovae and Faint supernovae. (5) 90-140 Msolar stars produce Luminous SNe, like SNe 2007 bi and 2006 gy (6) 140-300 Msolar stars become pair-instability supernovae which could be Luminous supernovae (SNe 2007 bi and 2006 gy). (7) Very massive stars with M>~300 Msolar undergo core-collapse to form intermediate mass black holes. Some SNe could be more Luminous supernovae (like SN 2006 gy).
