One of the central ideas of the present proposal is to connect the covariant density functional description of dense baryonic matter with its microscopic description based on the T-matrix theory. This theory is constrained by the experimental studies of nucleon-nucleon scattering and nucleonic-bound states. Qualitatively new density functionals will be developed and deployed to study compact stars. We will also study the structure and stability of hybrid stars allowing for multiple phase transitions as is the case when color superconducting phases are taken into account. A major step will be the computations of the oscillation modes of such stars and the assessment of their stability. We will assess the mass-radius diagram of compact stars, in light of the new stability conditions of hybrid compact stars.

本方案的核心思想之一是将重子物质的协变密度泛函描述与基于T-矩阵理论的重子物质微观描述联系起来。这一理论受到核子-核子散射和核子束缚态实验研究的限制。质量新的密度泛函将被开发和部署，以研究紧凑型恒星。我们还将研究混合星的结构和稳定性，允许多个相变的情况下，考虑到颜色超导相。一个主要步骤将是计算这些恒星的振荡模式并评估其稳定性。我们将评估致密星的质量半径图，根据新的混合致密星的稳定性条件。
