Impact of current uncertainties in the 12C+12C nuclear reaction rate on intermediate-mass stars and massive white dwarfs
Francisco C. De Gerónimo, Marcelo M. Miller Bertolami, Tiara Battich +6
Recent determinations of the total rate of the 12C+12C nuclear reaction show non-negligible differences with the reference reaction rate commonly used in previous stellar simulatio…
