Evidence for CME--CME Interaction in a Magnetic-Cloud-Like Ejecta: Insights from Multipoint Observations and Polytropic Analysis
Jyoti Sheoran, Vaibhav Pant, Eva Weiler +5
Using in-situ observations from Solar Orbiter, STEREO-A, and Wind, we investigate the heliospheric evolution of an interplanetary coronal mass ejection (ICME). The magnetic ejecta…
Turbulent Properties of Interplanetary Coronal Mass Ejections Observed by Solar Orbiter in the Inner Heliosphere
Jyoti Sheoran, Supratik Banerjee, Vaibhav Pant +2
We investigate the turbulent properties of 12 interplanetary coronal mass ejections (ICMEs) observed by Solar Orbiter between 0.29 and 1.0 AU. We analyze fluctuation power, spectra…
Inferring physical parameters of solar filaments from simultaneous longitudinal and transverse oscillations
Upasna Baweja, Vaibhav Pant, Iñigo Arregui +1
Context. Different modes of oscillations are frequently observed in solar prominences/filaments, and prominence seismology helps estimate important physical parameters like the mag…
Probing spectral line asymmetries due to the propagating transverse waves in the solar corona
Ambika Saxena, Vaibhav Pant, Tom Van Doorsselaere +1
Decades-long studies of asymmetric spectral lines in the solar corona suggest mass and energy transport from lower atmospheric layers to the corona. While slow magnetoacoustic wave…
Co-existence of longitudinal and transverse oscillations in polar plumes observed with Solar Orbiter/EUI
Upasna Baweja, Vaibhav Pant, S. Krishna Prasad +6
Magnetohydrodynamic (MHD) waves play a key role in heating the solar corona and driving the solar wind. Recent observations have shown the presence of slow magneto-acoustic and Alf…
