      The Type Ia supernova (SN Ia) LSQ14fmg exhibits exaggerated properties that may help to reveal the origin of the "super-Chandrasekhar" (or 03fg-like) group. The optical spectrum is typical of a 03fg-like SN Ia, but the ...

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) ...
