| Abstract: | We investigated the lower mass limitM
l
for the carbon detonation supernovae by testing the dynamical instability of the envelopes of red supergiants. It was found that the dependence ofM
l
on the mixing lengthl of convection is appreciable. As a smaller value ofl is assumed,M
l
becomes larger. It may be as large as 8M
 ifl is a third of the pressure scale-height. This is one of the ways to remove the difficulty of overproduction of iron-peak elements involved in the model of the carbon detonation supernovae. |
