**MOBSE** is a **customized** version of BSE (acronym for Binary Stellar Evolution Hurley et al. 2002). With respect to BSE, MOBSE is a population-synthesis code that **includes some important upgrades** for the evolution of **massive stars** both singles and in binary systems:

- new treatment for the
**natal kicks** velocities - up-to-date equations for metal-dependent
**stellar winds** including the dependence on the **Eddington factor** - recent models for core-collapse and electron-capture
**supernovae** (SNe) - prescriptions for
**pair-instability** and **pulsational-pair-instability** SNe - updated formulas to compute the
**core radii** **maximum initial mass** up to 150 Msun
