标题： Constraining String Gauge Field by Planet Perihelion Precession and Galaxy Rotation Curves

摘要： 我们对一个宇宙学模型进行了各种测试，在该模型中，弦规范场及其与物质的耦合被用来解释星系中恒星的旋转动力学。使用的观测数据包括近日点进动和星系旋转曲线。 我们求解了1）洛伦兹类力和2）一般幂律中心力扰动下的进动运动。对于后一种情况，推导出一个简单的规则来判断顺行/逆行运动。 我们将太阳系行星的进动归因于弦场的作用力，并计算了场强。 然后，我们用一个由太阳产生的一部分和另一个由银河系其他物质产生的背景组成的轮廓来拟合得到的场强。我们使用银河系旋转曲线来估计场强，并将其与通过进动发现的场强进行了比较。 还分析了另外22个星系的场强。这些强度形成一个跨越两个数量级的范围，并包含了银河系找到的值。 我们还从模型中推导出了场强、星系大小和光度之间的关系，并用22个星系的数据进行了验证。 显示英文摘要

摘要： We performed various tests on a cosmological model in which the string gauge field, and its coupling to matter, is used to explain the rotation dynamics of stars in a galaxy. Observations used include perihelion precession and galaxy rotation curves. We solved precession motions for perturbations of 1) a Lorenz-like force and 2) a general power law central force. For the latter case, a simple rule judging pro/retrograde motions is derived. We attributed the precession of solar system planets to the force due to the string field and calculated the field strengths. We then fitted the resultant field strengths with a profile consisting one part generated by the Sun and another background due to other matter in the Milky Way. We used the Milky Way rotation curve to estimate the field strength and compared it with the one found by precession. The field strengths in another 22 galaxies are also analyzed. The strengths form a range that spans 2 orders of magnitude and contains the value found for the Milky Way. We also deduced from the model a relation between field strength, galaxy size and luminosity and verified it with data of the 22 galaxies.
