ABSTRACT By assuming an aspherical stellar wind with an equatorial disc from a red giant, we investigate the production of Type Ia supernovae (SNe Ia) via a symbiotic channel. We estimate that the Galactic birthrate of SNe Ia via the symbiotic channel is between 1.03 × 10 −3 and 2.27 × 10 −5 yr −1 , while the delay time of SNe Ia has a wide range from ∼0.07 to 5 Gyr. The results are greatly affected by the outflow velocity and mass‐loss rate of the equatorial disc. Using our model, we discuss the progenitors of SN 2002ic and SN 2006X.
