SPIN-UP/SPIN-DOWN MODELS FOR TYPE Ia SUPERNOVAE
SPIN-UP/SPIN-DOWN MODELS FOR TYPE Ia SUPERNOVAE
In the single-degenerate scenario for Type Ia supernovae (SNe Ia), a white dwarf (WD) must gain a significant amount of matter from a companion star. Because the accreted mass carries angular momentum, the WD is likely to achieve fast spin periods, which can increase the critical mass, Mcrit, needed for …
