Table 2
Comparison between observational data about nova outbursts (Della Valle & Izzo 2020) and model results.
| Observational data | Rates | Numbers | |
|---|---|---|---|
| (whole disc, present-day) | (whole disc, present-day) | (solar vicinity, 9.2 Gyr of evolution) | |
| Nova systems | - | 0.0031 events/yr | 1.18 million |
| Nova outbursts | 25–30 events/yr | 31 events/yr | 11.8 billion |
| White dwarfs | - | 1.11 events/yr | 423 million |
Notes. Theoretical rates of formation of WDs and nova systems are also reported, though observed rates of formation of WDs and nova systems are not available. The legend for Table 1 applies here also.
