Microwave Polar Brightening and Its Connection to Polar Coronal Holes
Rohan Bose, Anshu Kumari, Vaibhav Pant +3
Polar brightening (PB) observed at microwave frequencies serves as an important probe to study the thermal and magnetic properties in the Sun's polar regions. Building on earlier s…
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…
Probing Solar Polar Regions
Yuanyong Deng, Hui Tian, Jie Jiang +45
The magnetic fields and dynamical processes in the solar polar regions play a crucial role in the solar magnetic cycle and in supplying mass and energy to the fast solar wind, ulti…
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…
