论文摘要
我们介绍了两个遥远的彗星C/2002 VQ94（线性）和29p/Schwassmann-Wachmann 1的光度研究结果分析，该结果是通过俄罗斯科学院特殊天体物理天文台的6M望远镜获得的。研究中的彗星表明，水冰升华区（以超过5 au的速度超过5 a）的升华区域。在研究的彗星的光谱中，我们发现了CO+和N2+发射。这种发射的存在可能会说彗星在太阳系的外部形成，在温度下的原球云中，在温度<= 25 K处形成。我们发现，彗星C/2002 VQ94（线性）的电离层的光度最大（在CO+滤波器中）相对于2.4 arcsec（3. 4.4 arc）移动。从方向到太阳63度。使用特殊过滤器来处理图像，我们在29p/schwassmann-Wachmann 1彗星的灰尘昏迷中选择了活跃的结构（JET）。
We present an analysis of the results of photometric investigations of two distant comets, C/2002 VQ94 (LINEAR) and 29P/Schwassmann-Wachmann 1, obtained with the 6m telescope of the Special Astrophysical Observatory of the Russian Academy of Sciences. The comets under study demonstrate sufficient activity out of the zone of water ice sublimation (at heliocentric distances longer than 5 AU). In the spectra of the investigated comets, we found the CO+ and N2+ emission. The presence of this emission may say that the comets were formed in the outer parts of the Solar System, in a protoplanetary cloud at a temperature <=25 K. We found that the photometric maximum of the ionosphere (in the CO+ filter) of the comet C/2002 VQ94 (LINEAR) is shifted relative to the photometric center of the dust coma by 1.4 arcsec (7.44*10^3 km) in the direction deflected by 63 deg from the direction to the Sun. Using special filters to process the images, we picked out active structures (jets) in the dust coma of the 29P/Schwassmann-Wachmann 1 comet.
