dc.descriptionGamma-ray bursts (GRBs) must originate from low baryon load, ultrarelativistic outflows; however, slower, more baryon-rich outflows (BROs) should also arise in connection with GRBs as ``circum-jet winds'' and/or ``failed GRBs''. We study the possibility of nucleosynthesis within such BROs by conducting detailed reaction network calculations in the framework of the fireball model, showing that they can be interesting sites for synthesis of heavy neutron capture elements, as well as of light elements such as deuterium. These products may be observable in the companion stars of black hole binary systems or in extremely metal-poor stars, offering an interesting probe of conditions in the central engine.
