Number abundance of and energy production due to 40K.
|Type||X(40K)||(10-8 erg s-1 g-1)|
|× 10-7||at 4.6 Gyr|
|SNII 15 M⊙||2.48||7.6|
|SNII 20 M⊙||326.5||996.7|
Notes. Number abundance is calculated as 40K atoms relative to total refractory atoms, approximated by including C, O, Mg, Fe, Si, Al, and S. Supernova abundances are from Rauscher et al. (2002).
