- W2052392568 abstract "Since particles receive the velocity behind moving cosmic strings, wakes are formed from dark matter and baryonic matter. These wakes will fragment into the first systems of mass M ≃107(Gµ/10-6)3 (βst γst)3 (1+zi)1.5 /(1+zf)3 M⊙, where zi, zf, µ, βmboxst and γst are the epoch the cosmic string traverse, the epoch the fragmentation occurs, the line density, the velosity of the strings and γst=(1-β2st)-1/2 in units of c=1. The shock waves in the baryonic matter appear in the wakes after the epoch z≃790(Gµβstγst/10-6). The baryon gas clouds may contract due to H2 cooling after z≃102 and Population III stars with masses of 10-1∼102M⊙ may be fragmented within such first sysetms. The effects of such Population III stars on the surrounding space are briefly discussed." @default.
