THEMIS observations of compressional Pc5 pulsations in the dawn- and duskside magnetosphere
Sibeck, D. G.; Korotova, G. I.
We present case and statistical studies of compressional Pc5 pulsations observed by the THEMIS spacecraft in the dawn- and duskside magnetosphere from 2007 to 2011. A case study provides evidence for compressional Pc5 pulsations in the dawnside magnetosphere following the arrival of particles injected by a substorm and the subsequent growth of the…
Some observational properties of the Herbig Be Star AS 310
Bakış, Volkan; Alishov, S. A.; Ismailov, Nariman Z. +2 more
The results of spectral and photometric studies of Herbig Be-type star AS 310 have been presented. Photometric observations in the BVRcIc bands performed in 2016-2021 showed that the amplitude of the seasonal brightness variations of the star changes smoothly in different years and reaches a maximum of approximately around Δ V ∼ 0.6 mag in 2018. T…
Type II radio bursts and space weather phenomena: A statistical study
Chandra, Ramesh; Miteva, Rositsa; Koleva, Kostadinka +2 more
In this paper, we present for the first time a comprehensive statistical study between type II radio bursts from the metric (m) to the dekameric–hectometric (DH) domain and their associated solar and space weather (SW) phenomena, namely, solar flares (SFs), sunspot (SN) configurations, filament eruptions, coronal mass ejections (CMEs), their inter…
Dynamical modeling and characteristic analysis of orbits around a comet
He, Yuchen; Wang, Yue; Tian, Lin
As a frontier field of deep-space explorations, the study of comets is of great value to planetary scientific research, resource exploration, and planetary defense. To date, only the ESA's Rosetta spacecraft successfully orbited the comet 67P. The orbital dynamical environment around comets is more complex than that of other small bodies, making t…
