Cosmic Rays in Star Forming Environments : Proceedings of the Second Session of the Sant Cugat Forum on Astrophysics These are the proceedings of the Sant Cugat Forum 2nd Workshop on Cosmic ray Induced Phenomenology in Stellar Environments held April 16 19 2012. The aim of this Workshop was to address the current knowledge and challenges of high energy emission from stellar environments at all scales and provide a comprehensive review of the state of the field from the observational to the theoretical perspectives. In the meeting the prospects for possible observations with planned instruments across the multi wavelength spectrum were analyzed and also how they impact on our understanding of these systems
