Abstract We present an investigation of halo coronal mass ejections (HCMEs) kinematics and other facts about the HCMEs. The study of HCMEs is very important because HCMEs are regarded as the main causes of heliospheric and geomagnetic disturbances. In this study, we have investigated 313 HCMEs observed during 1996-2012 by LASCO, coronal holes, and solar flares. We find that HCMEs are of two types: accelerated HCMEs and decelerated HCMEs. The mean space speed of HCMEs is 1283 km/s while the mean speed of decelerated HCMEs and accelerated HCMEs is 1349 km/s and 1174 km/s, respectively. The investigation shows that 1 (0.3%) HCME was associated with class A SXR, 14 (4.7%) HCMEs were associated with class B SXR-flares, 87 (29.4%) HCMEs were associated with class C SXR-flares, 125 (42.2%) HCMEs were associated with class M SXR-flares and 69 (23.3%) HCMEs were associated with class X SXR-flares. The speed of HCMEs increases with the importance of solar SXR-flares. The various results obtained in the present analysis are discussed in the light of the existing scenario of heliospheric physics.

晕日冕物质抛射的一些运动学

摘要 我们对晕日冕物质抛射 (HCME) 运动学和其他关于 HCME 的事实进行了调查。HCMEs 的研究非常重要，因为 HCMEs 被认为是日光层和地磁扰动的主要原因。在这项研究中，我们调查了 1996-2012 年由 LASCO、日冕洞和太阳耀斑观测到的 313 个 HCME。我们发现 HCME 有两种类型：加速的 HCME 和减速的 HCME。HCMEs 的平均空间速度为 1283 km/s，而减速 HCMEs 和加速 HCMEs 的平均速度分别为 1349 km/s 和 1174 km/s。调查显示 1 (0.3%) HCMEs 与 A 类 SXR 相关，14 (4.7%) HCMEs 与 B 类 SXR 耀斑相关，87 (29.4%) HCMEs 与 C 类 SXR 耀斑相关，125 (42.2 %) HCME 与 M 类 SXR 耀斑和 69 (23. 3%) HCME 与 X 类 SXR 耀斑有关。HCME 的速度随着太阳 SXR 耀斑的重要性而增加。根据现有的日光层物理学情景讨论了本分析中获得的各种结果。
