Distinct polytropic behavior of plasma during ICME-HSS Interaction
Kalpesh Ghag, Anil Raghav, Zubair Shaikh +3
Interplanetary Coronal Mass Ejections (ICMEs) and High Speed Streams (HSSs) are noteworthy drivers of disturbance of interplanetary space. Interaction between them can cause severa…
In-situ Observation Of Alfv'en Waves In Icme Shock-Sheath Indicates Existence Of Alfv'enic Turbulence
Anil Raghav, Zubair Shaikh, Omkar Dhamane +3
The dynamic evolution of coronal mass ejection (CME) in interplanetary space generates highly turbulent, compressed, and heated shock-sheath. This region furnishes a unique environ…
Causes of the Diurnal Variation observed in -ray Spectrum using NaI (Tl) Detector
Gauri Datar, Geeta Vichare, C. Selvaraj +2
Present paper studies the -ray spectrum observed using NaI(Tl) scintillation detector over a year. The paper reports the presence of a distinct diurnal pattern in the total numb…
Torsional Alfven wave embedded ICME magnetic cloud and corresponding geomagnetic storm
Anil N. Raghav, Ankita Kule, Ankush Bhaskar +3
The energy transfer during the interaction of large-scale solar wind structure and the Earth's magnetosphere is the chronic issue in space-weather studies. To understand this, rese…
Does the Alfvén wave disrupt the large-scale magnetic cloud structure?
Anil N. Raghav, Ankita Kule
Alfvén waves are primal and pervasive in space plasmas and significantly contributes to microscale fluctuations in the solar wind and some heliospheric processes. Here, we demonstr…
The first observable in-situ evidence of Alfvenic turbulence in shock-sheath
Anil N. Raghav, Zubair I. Shaikh
The dynamic evolution of coronal mass ejection (CME) in interplanetary space generates highly turbulent, compressed and heated shock-sheath. This region furnishes a unique environm…
