SEVN (presented in Spera, Mapelli & Bressan 2015) is our new open source population-synthesis code. The mass spectrum of black
holes we predicted with SEVN was recently used by the LIGO-Virgo collaboration to constrain the metallicity of the progenitors
of GW150914 (Abbott et al. 2016).
SEVN includes (1) up-to-date stellar evolution (through look-up tables), (2) binary evolution, (3) five different recipes for
core-collapse supernovae, and (4) an up-to-date formalism for pair-instability and pulsational pair-instability supernovae.
Moreover, SEVN is designed to be interfaced with direct-summation N-body codes (such as STARLAB and HiGPUs). You can
download the most recent stable version going to our gitlab project.
Our group (ForDyS) is still developing new feature in SEVN. In particular I am the main developer of two the modules which handle the common-envelope
phase and the generation of supernovae kick.
