On the formation of solar wind & switchbacks, and quiet Sun heating
Vishal Upendran, Durgesh Tripathi
The solar coronal heating in quiet Sun (QS) and coronal holes (CH), including solar wind formation, are intimately tied by magnetic field dynamics. Thus, a detailed comparative stu…
Properties of the C II 1334 Å line in Coronal Hole and Quiet Sun as observed by IRIS
Vishal Upendran, Durgesh Tripathi
Coronal Holes (CHs) have subdued intensity and net blueshifts when compared to Quiet Sun (QS) at coronal temperatures. At transition region temperatures, such differences are obtai…
On the Impulsive Heating of Quiet Solar Corona
Vishal Upendran, Durgesh Tripathi
The solar corona consists of a million-degree Kelvin plasma. A complete understanding of this phenomenon demands the study of Quiet Sun (QS) regions. In this work, we study QS regi…
Global Earth Magnetic Field Modeling and Forecasting with Spherical Harmonics Decomposition
Panagiotis Tigas, Téo Bloch, Vishal Upendran +6
Modeling and forecasting the solar wind-driven global magnetic field perturbations is an open challenge. Current approaches depend on simulations of computationally demanding model…
