Alfv\'en Pulse Driven Spicule-like Jets in the Presence of Thermal Conduction and Ion-Neutral Collision in Two-Fluid Regime

Autor: Srivastava, A. K., Singh, Anshika, Singh, Balveer, Murawski, K., Zaqarashvili, T. V., Yuan, D., Scullion, E., Mishra, Sudheer K., Dwivedi, B. N.

We present the formation of quasi-periodic cool spicule-like jets in the solar atmosphere using 2.5-D numerical simulation in two-fluid regime (ions+neutrals) under the presence of thermal conduction and ion-neutral collision. The non-linear, impulsi

Numerical Simulations of the Decaying Transverse Oscillations in the Cool Jet

Autor: Srivastava, Abhishek K., Singh, Balveer

We describe a 2.5D MHD simulation describing the evolution of cool jets triggered by initial vertical velocity perturbations in the solar chromosphere. We implement random velocity pulses of amplitude 20-50 km/s between 1 Mm and 1.5 Mm, along with va

Evolution of Kelvin-Helmholtz Instability in the Fan-Spine Topology

Autor: Mishra, Sudheer K., Singh, Balveer, Srivastava, A. K., Kayshap, Pradeep, Dwivedi, B. N.

We use multiwavelength imaging observations from the Atmospheric Imaging Assembly (AIA) onboard the Solar Dynamics Observatory (SDO) to study the evolution of Kelvin-Helmholtz (K-H) instability in a fan-spine magnetic field configuration. This magnet

On modelling the kinematics and evolutionary properties of pressure pulse driven impulsive solar jets

Autor: Singh, Balveer, Sharma, Kushagra, Srivastava, Abhishek K.

In this paper, we describe the kinematical and evolutionary properties of the impulsive cool jets in the solar atmosphere using numerical simulation by Godunov-type PLUTO code at two different strength of the quiet-Sun magnetic field (B=56, 112 Gauss
