论文摘要
我们计算了天体物理和宇宙学来源的红色和蓝色移位。特别是，我们考虑了低，中间和高重力能域。因此，我们处理二元系统的地球 - 火星作为低能景观，而白色矮人和中子星则作为更高的能源。为此，我们考虑了球形的Schwarzschild -De Sitter Spacetime和一个轴向对称的Zipoy -Voorhees度量，以建模上述所有上述系统。可行的结果来自与Zipoy -voorhees度量的建模中子星和白色矮人，其中四极效应是相关的，并使用Schwarzschild -de Sitter SpaceTime对太阳系对象进行了构架。在第一种情况下，大$δ$参数似乎是最爱，导致可接受的界限主要是中子星。在第二种情况下，一旦将宇宙学常数带到普朗克卫星的最佳拟合度后，我们就会证明对月球和卫星激光的不兼容的红色和蓝色移位。为了治愈这个问题，我们建议粗粒的实验设置，并提出phobos来制定卫星激光范围，以获得更合适的红色和蓝移间隔，可能比当前的实验界限更兼容。还辩论了对宇宙紧张局势的影响。
We compute the red and blue shifts for astrophysical and cosmological sources. In particular, we consider low, intermediate and high gravitational energy domains. Thereby, we handle the binary system Earth - Mars as low energy landscape whereas white dwarfs and neutron stars as higher energy sources. To this end, we take into account a spherical Schwarzschild - de Sitter spacetime and an axially symmetric Zipoy - Voorhees metric to model all the aforementioned systems. Feasible outcomes come from modelling neutron stars and white dwarfs with the Zipoy - Voorhees metric, where quadrupole effects are relevant, and framing solar system objects using a Schwarzschild - de Sitter spacetime. In the first case, large $δ$ parameters seem to be favorite, leading to acceptable bounds mainly for neutron stars. In the second case, we demonstrate incompatible red and blue shifts with respect to lunar and satellite laser ranging expectations, once the cosmological constant is taken to Planck satellite's best fit. To heal this issue, we suggest coarse-grained experimental setups and propose Phobos for working out satellite laser ranging in order to get more suitable red and blue shift intervals, possibly more compatible than current experimental bounds. Implications to cosmological tensions are also debated.
