This workshop brings together experts in the fields of star- and planet formation, astrochemistry, planetary science, our Solar System, and prebiotic chemistry to discuss current knowledge and questions relating to the role of sulfur in the formation of minor bodies, planetary systems, exoplanets, and prebiotic chemistry. The main topics of the meeting are: (1) sulfur chemistry in molecular clouds, (2) sulfur chemistry in planet- forming disks, (3) formation of rocky planets: geophysical importance of sulfur, (4) role of sulfur in prebiotic chemistry, (5) sulfur in our Solar System. The workshop aims to review the latest knowledge on the sulfur trail from molecular clouds to the formation of planets and to highlight the key questions to be answered in the next decade.
