“质心说的行星轨道是摆线”论文，是推广科学质心说摆线的真理，宣传社会和谐。三百多年了，天文学应该用质心说更新。 摄动理论是从日心说椭圆而来，后来添加了质心说等摄动函数和轨道根数，从日心说改成质心说，就不是恒等变换。科学上面，两个相反的概念，是绝对不允许混淆的。让科学真相普及全世界吧！
牛顿质心说是天体运行规律，也是平等、民主的科学依据。人们只知道日心说的椭圆，不知道质心说。三百年后，今天，必须用质心说为它命名。本文用时针针尖运动，证明了质心说的行星轨道是摆线。这不仅是科学问题，也是社会问题。我们要普及质心说，使社会和谐、太平。
水星引力辐射与脉冲双星引力辐射的比较
水星进动 推迟引力 推迟引力辐射 单极、偶极和四极引力辐射
2015/5/29
对水星近日点进动的观测已积累有百余年的资料, 并充分考虑了天文坐标系的旋转和其它行星的摄动, 是可靠的. 我们已用推迟引力求解了水星近日点的进动，与天文观测结果符合得极好, 推迟引力成为唯一能够成功解释水星进动的引力理论。由推迟引力辐射场计算出的水星近日点的世纪进动值与观测值符合得极好，这意味着水星近日点的进动正是存在引力辐射场的最可信证据, 水星近日点的世纪进动也成为检验引力辐射理论的试金石。T...
水星引力辐射与强场推迟引力
水星进动 推迟辐射引力 单极、偶极和四极引力辐射 强场推迟引力
2015/5/29
对水星近日点进动的观测已有长期可靠的数据. 我们已用推迟引力求解了水星近日点的进动，与天文观测结果符合得极好, 推迟引力成为唯一能够成功解释水星进动的引力理论。由推迟引力的切向引力辐射场计算出的水星近日点的世纪进动值与观测值符合得极好，这意味着水星近日点的进动正是存在引力辐射场的最可信证据, 水星近日点的世纪进动也成为检验引力辐射理论的试金石。鉴于无法排除其它星体对脉冲双星的摄动, 也无法独立确定...
Jovian Early Bombardment: planetesimal erosion in the inner asteroid belt
Asteroids Impacts Jupiter Solar System Formation Solar System Evolution
2012/2/23
The asteroid belt is an open window on the history of the Solar System, as it preserves records of both its formation process and its secular evolution. The progenitors of the present-day asteroids fo...
