Milky Way disc (R>2 kpc) observational constraints compared to predicted values.
| Observations | Predictions | |
|---|---|---|
| SFR [M⊙ yr−1] | 0.65–3(a) | 2.24 |
| Gas mass [109 M⊙] | 8.1–4.5(b) | 6.4 |
| Stellar mass [1010 M⊙] | 3.−4.(c) | 3.7 |
| Infall rate [M⊙ yr−1] | 0.6–1.6(d) | 0.65 |
| Type II SNe [events century−1] | 0.4–2.0(e) | 0.88 |
| Type Ia SNe [events century−1] | 0.1–0.5(e) | 0.2 |
Notes. Column 1 refers to the quantity in exam, column 2 to the observed value and the column 3 to the predicted value. The two models differ for the nucleosynthesis only, therefore all the other predictions are the same in the two cases. The observed values are taken from the following references. (a)Prantzos et al. (2011), Chomiuk & Povich (2011). (b)Kubryk et al. (2015). (c)Flynn et al. (2006). (d)Marasco et al. (2012), Lehner & Howk (2011). (e)Cappellaro & Turatto (1997).
