论文摘要
对彗星C/2013 A1（壁板弹簧）的光度数据进行了分析，该数据是在大型中心距离（4.1 AU接近）的观测值中进行的。 C/2013 A1（壁板弹簧）表现出激烈的活动，尽管距离地向上心较大。分析了彗星昏迷的形态。测量以下参数：颜色指数V-R，彗星灰尘S'反射率的归一化光谱梯度以及灰尘生产速率AF \ r {HO}。与火星近距离接触后，对彗星轨道的演变进行了数值模拟。在一百年的时间内，获得了彗星的开普勒轨道元素的最可能值。经过所有太阳系行星的轨道后，彗星的轨道几乎保持了抛物线。
An analysis is presented for the photometric data on comet C/2013 A1 (Siding Spring) from observations at a large heliocentric distance (near 4.1 AU). Comet C/2013 A1 (Siding Spring) displays intense activity despite the relatively large heliocentric distance. The morphology of the comet's coma is analyzed. The following parameters are measured: the color indices V-R, the normalized spectral gradient of the reflectivity of the comet's dust S', and the dust production rate Af\r{ho}. A numerical simulation is performed for the evolution of the comet's orbit after a close encounter with Mars. The most probable values are obtained for the Keplerian orbital elements of the comet over a hundred-year period. The comet's orbit remains nearly parabolic after passing the orbits of all the Solar System planets.
