论文摘要
Klioner等。已经使用Gaia EDR3数据直接使用类星体的明显适当运动在银河系中直接测量太阳系的加速度。我在这里表明，这种单一的绝对加速度测量与从脉冲星轨道衰变获得的相对加速度结合在一起，使人们可以确定所有描述当地银河环境动态的参数，包括Sun $ v_0 = 244 = 244 \ pm 8 $ km/s/s and suteratival $ km/s/s的衍生物$ v'___0 = 2 $ kp， Oort常数，以及有关LSR的太阳运动。这是这些参数的第一个确定，仅使用相对论的一般理论而无需其他假设。
Klioner et al. have used the Gaia EDR3 data to directly measure the solar system's acceleration within the Milky Way using the apparent proper motions of quasars. Here I show that this single absolute acceleration measurement in combination with relative accelerations obtained from pulsar orbital decay allows one to determine all of the parameters describing the dynamics of our local Galactic environment, including the circular velocity at the Sun $V_0 = 244 \pm 8$ km/s and its derivative $V'_0 = 2 \pm 9$ km/s/kpc, the local angular frequency, the Oort constants, and the Sun's motion with respect to the LSR. This is the first determination of these parameters that only uses the general theory of relativity without the need for additional assumptions.
