Description

► The effects of passing stars on the flux of observable comets is studied. ► Massive stars inject observable comets much more efficiently than light stars do. ► The long term synergy between stars and Galactic tide is explained. ► Stars send comets into orbits from which the tides may make them observable. ► Single massive stars may increase the flux significantly for more than 100 Myr.
