Gamma-Ray Bursts and Type Ic Supernova SN 1998bw
Recently a Type Ic supernova, SN 1998bw, was discovered coincident with a gamma-ray burst, GRB 980425. The supernova had unusual radio, optical, and spectroscopic properties. Among other things, it was especially bright for a Type Ic both optically and in the radio, and it rose quickly to maximum. We explore here models based upon helium stars in the range 9-14 M⊙ and carbon-oxygen stars 6-11 M⊙, which experience unusually energetic explosions (kinetic energy 0.5-2.8 × 1052 ergs).
