论文摘要
我们以四极性WI模式重新访问星星志学，并以其基本和第一个夸张的方式提出了普遍的关系。与文献中提出的关系相反，我们的普遍关系能够包括慢速稳定的杂种恒星，这些恒星在考虑缓慢的尖锐的强体夸克相过渡时出现。我们表明，如果测量给定脉动对象的基本模式的频率和阻尼时间，则可以推断出其质量，半径和无量纲的潮汐变形。此外，我们表明，此类估计的误差小于质量和半径的百分之几。对于无量纲潮汐变形性，对于具有$ M \ gtrsim 1.4 \，m_ \ odot $的紧凑对象，这些错误通常小于〜100％。与以前的普遍关系进行比较表明，这项工作中提出的关系可以更好地估计完全稳定的紧凑物体的质量和半径。
We revisit asteroseismology with quadrupolar wI modes and present universal relationships for its fundamental and first overtone. In contrast to relationships proposed in the literature, our universal relationships are capable of including slow stable hybrid stars that appear when considering slow sharp hadron-quark phase transitions. We show that, if the frequency and damping time of the fundamental mode of a given pulsating object are measured, its mass, radius, and dimensionless tidal deformability can be inferred. Moreover, we show that the errors of such estimates are smaller than a few percent for the mass and radius. For the dimensionless tidal deformability, the errors are -- for compact objects with $M\gtrsim 1.4\,M_\odot$ -- in general smaller than ~100%. Comparison with previous universal relationships shows that the ones proposed in this work produce better estimates of the mass and radius of totally stable compact objects.
