Partial Null Point Reconnection of an Eruptive Filament
Pooja Devi, Cristina H. Mandrini, Ramesh Chandra +4
Solar filaments are cool and dense plasma structures suspended in the solar corona against gravity. We present observations of a quiescent filament eruption that occurs on 13 July…
Band Splitting in m-Type II radio Bursts and their Role in Coronal Parameter Diagnostics
Pooja Devi, Ramesh Chandra, Rositsa Miteva +2
Type II radio bursts are signatures of shock waves generated by solar eruptions, observed at radio wavelengths. While metric (m) type II bursts originate in the lower corona, their…
Two Cases of Non-Radial Filament Eruption and Associated CME Deflection
Kostadinka Koleva, Ramesh Chandra, Pooja Devi +2
The purpose of this paper is to analyze the multi-wavelength and multi-instrument observations of two quiescent filament eruptions as well as the deflection of associated CMEs from…
EUV Wave and Coronal Seismology
Pooja Devi, Ramesh Chandra, Arun Kumar Awasthi +2
We present an investigation of the Extreme-Ultraviolet (EUV) wave linked to the flare that occurred on 28 October 2021, along with the associated coronal loop oscillation and type…
Type II radio bursts and space weather phenomena: A statistical study
Pooja Devi, Rositsa Miteva, Ramesh Chandra +2
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 a…
Counter-Streaming Velocities in a Quiescent Filament
Garima Karki, Brigitte Schmieder, Pascal Demoulin +3
Filaments/prominences are cold plasma (~ 10000 K) embedded in the solar corona, two orders of magnitude hotter. Filament plasma is structured by the magnetic field in thin elongate…
