Impact flux of asteroids and water transport to the habitable zone in binary star systems [PDF]

open access: yes, 2014
By now, observations of exoplanets have found more than 50 binary star systems hosting 71 planets. We expect these numbers to increase as more than 70% of the main sequence stars in the solar neighborhood are members of binary or multiple systems.
