(a) Three different initial mass functions (IMFs). The Scalo (1986) and Miller & Scalo (1979) IMFs are two different parameterizations of the locally observed stellar population, and the tilted Scalo IMF is obtained by adding a constant β = 1.69 to the power‐law index in each segment of the Scalo IMF, while keeping the value of the IMF fixed at 4 M_☉. All three IMFs are normalized to an integral of 1 M_☉. (b) Carbon yields from stars of different masses (M_12C, in solar masses), folded in with the three different IMFs. In all cases, most of the carbon is produced by ~3–6 M_☉ stars.
