We study the occurrence of 2 flavour color superconductivity in compact stars and the consequences for the configurations. The phases of 2 color superconducting (2SC) and color spin locking (CSL) and the corresponding equations of state are investigated. Signatures for the mass-radius relation for the configurations and the influence of the energy gaps in the cooling behaviour are presented and compared with observational candidates. • Partially supported by DAAD, Helmholtz Stiftung and Landesgraduiertenförderung MV
