A small, but important "by product" of star formation is the formation of planetary systems.
Tradiationally this problem is regarded independently from the star formation process.
I will argue in this talk/poster that the very initial parameters in the early phase of the
formation of a star have influence on the outcome in the late phase: the formation of
a solar system. In particular the intial rotation rate of the collapsing cloud is a crucial
parameter. It will influence the life time of the disk (and thus the window of opportunity
for planet formation), the chemical nature of the dust (the building material for planets),
and the nature and distribution of ices and organics in the disk (raw material for Earth's
oceans and life).
