白矮星与启示
White dwarfs and revelations
摘要：
我们使用最新的，完整的和独立的测量质量和半径的白矮星的双星绑定类的非平凡的修改后的引力理论，可行的GW 170817/GRB 170817，利用其对质量半径关系的恒星。我们表明，在最新的数据的不确定性是足够小的残余的进化效应，最显着的核心成分，有限的温度和信封结构的影响，现在必须占如果正确的结论的性质，重力。我们的模型修正导致有限的温度和信封的基础Hamada-Salpeter冷状态方程，并得出一致的边界上可能修改的重力在恒星的内部，发现$Y< 0.14$在95\%的置信度，一个改进的三个因素相对于以前的边界。最后，我们的分析揭示了引力理论和白矮星精确化学组成之间的一些基本简并性。
英文摘要：
We use the most recent, complete and independent measurements of masses and radii of white dwarfs in binaries to bound the class of non-trivial modified gravity theories, viable after GW170817/GRB170817, using its effect on the mass-radius relation of the stars. We show that the uncertainty in the latest data is sufficiently small that residual evolutionary effects, most notably the effect of core composition, finite temperature and envelope structure, must now accounted for if correct conclusions about the nature of gravity are to be made. We model corrections resulting from finite temperature and envelopes to a base Hamada-Salpeter cold equation of state and derive consistent bounds on the possible modifications of gravity in the stars' interiors, finding that $Y< 0.14$ at 95\% confidence, an improvement of a factor of three with respect to previous bounds. Finally, our analysis reveals some fundamental degeneracies between the theory of gravity and the precise chemical makeup of white dwarfs.
