论文摘要
由于径向速度方法，检测到许多系外行星，根据该方法，二元系统在其质量中心周围的运动可以产生宿主恒星发出的光的多普勒效应的周期性变化。这些变化受到牛顿和非牛顿的扰动的影响。因此，系外行驶系统可以测试重力理论替代一般相对论。在本文中，我们考虑了标准模型扩展（可用于测试所有可能的洛伦兹违规行为的模型）对径向速度扰动的影响，并提出合适的系外行星配置和检测技术的改进可能有助于获得对模型参数的新约束。
Many exoplanets were detected thanks to the radial velocity method, according to which the motion of a binary system around its center of mass can produce a periodical variation of the Doppler effect of the light emitted by the host star. These variations are influenced by both Newtonian and non-Newtonian perturbations to the dominant inverse-square acceleration; accordingly, exoplanetary systems lend themselves to test theories of gravity alternative to General Relativity. In this paper, we consider the impact of Standard Model Extension (a model that can be used to test all possible Lorentz violations) on the perturbation of radial velocity, and suggest that suitable exoplanets configurations and improvements in detection techniques may contribute to obtain new constraints on the model parameters.
