Solar abundance of manganese: a case for near Chandrasekhar-mass Type la supernova progenitors

Seitenzahl, Ivo; Cescutti, C; Röpke, F K; Ruiter, Ashley; Pakmor, R


Manganese is predominantly synthesised in Type Ia supernova (SN Ia) explosions. Owing to the entropy dependence of the Mn yield in explosive thermonuclear burning, SNe Ia involving near Chandrasekhar-mass (MCh) white dwarfs (WDs) are predicted to produce Mn-to-Fe ratios that significantly exceed those of SN Ia explosions involving sub-Chandrasekhar mass primary WDs. Of all current supernova explosion models, only SN Ia models involving near-MCh WDs produce [Mn/Fe] ≳ 0.0.
