...Magnetic fields generated by differential rotation in radiative regions have been implemented following the work of Spruit (2002) and in the same fashion as in Petrovic et al. (2005) and Heger et al. (2005)....

...We refer to Spruit (2002) for a description of the physics of the dynamo loop and to Maeder & Meynet (2003), Maeder & Meynet (2004) and Heger et al. (2005) for a discussion of its inclusion in stellar evolution codes....

...As expected, these fields are generated only in radiative regions of the star and Bφ > Br (Spruit 2002)....

...If the estimates of magnetic torques by Spruit (2002) are valid, then single stars are unlikely to produce collapsars and rotation is probably not a factor in the explosion of common supernovae....

...Recently, Spruit (2002) has discussed a ‘‘ dynamo ’’ mechanism based on the interchange instability that allows the estimation of magnetic torques to be included in models for stellar evolution....

...If only these known processes are included, pre-supernova cores rotate much too fast to explain the majority of supernovae (Heger et al. 2000), though they may rotate at the right rate for the collapsar model of gamma-ray bursts (McFadyen et al. 2001 and references therein)....

...The very small degree of differential rotation in the core of the Sun, and the small difference in rotation rate between the core and the convective envelope (Schou et al. 1998; Charbonneau et al. 1999) requires the presence a process with two special properties....

...This view is much closer to semiempirical models of the cycle like those of Leighton (1969), the development of which was eclipsed by the mathematically more interesting turbulent dynamo models....
