度量仿射重力对类地行星轮廓的影响
Metric-affine gravity effects on terrestrial (exo-)planets profiles
摘要：
对类地行星中常见的六种固体物质，得到了均匀冷球的质量-半径关系。在Palatini $f(\mathcal R)$引力的框架下，我们讨论了（外）行星轮廓中的一个附加简并性以及从我们的发现中得出的它们的性质。此外，一个新的重力测试已被提出：这里提出的结果将允许测试和约束重力模型，通过使用地震和大地震获得的地震数据。
英文摘要：
Mass-radius relations of homogeneous cold spheres are obtained for six solid materials commonly found in terrestrial planets. An additional degeneracy in the (exo-)planets' profiles is discussed together with their properties concluded from our findings in the framework of Palatini $f(\mathcal R)$ gravity. Moreover, a new test of gravity has been proposed: The results presented here will allow to test and to constrain models of gravity by the use of seismic data acquired from earthquakes and marsquakes.
