Effect of the Heliospheric State on CME Evolution
Fithanegest Kassa Dagnew, Nat Gopalswamy, Solomon Belay Tessema +2
The culmination of solar cycle 24 by the end of 2019 has created the opportunity to compare the differing properties of coronal mass ejections (CMEs) between two whole solar cycles…
Intercycle and intracycle variation of halo CME rate obtained from SOHO/LASCO observations
Fithanegest Kassa Dagnew, Nat Gopalswamy, Solomon Belay Tessema +3
We report on the properties of halo coronal mass ejections (HCMEs) in solar cycles 23 and 24. We compare the HCMEs properties between the corresponding phases (rise, maximum, and d…
A comparison of CME expansion speeds between solar cycles 23 and 24
Fithanegest Kassa Dagnew, Nat Gopalswamy, Solomon Belay Tessema
We report on a comparison of the expansion speeds of limb coronal mass ejections (CMEs) between solar cycles 23 and 24. We selected a large number of limb CME events associated wit…
The shock driving capability of a CME inferred from multiwavelength observations
Fithanegest Kassa Dagnew, Nat Gopalswamy, Solomon Belay Tessema +4
The radial speed of a coronal mass ejection (CME) determines the shock-driving capability of a CME as indicated by the presence of a type II radio burst. Here we report on the Apri…
On utmost multiplicity of hierarchical stellar systems
Y. M. Gebrehiwot, D. A. Kovaleva, A. Y. Kniazev +5
According to theoretical considerations, multiplicity of hierarchical stellar systems can reach, depending on masses and orbital parameters, several hundred, while observational da…
