Source Surface Height Optimisation for Improved Solar Wind Velocity Forecasting Across Solar Cycles 23, 24 and 25
Sandeep Kumar, Nandita Srivastava, Dana-Camelia Talpeanu
The potential field source surface (PFSS) model is a cornerstone of many state-of-the-art space weather forecasting frameworks. It includes a single physical free parameter, the so…
Propagation Characteristics of the April 21, 2023 CME
Sandeep Kumar, Nandita Srivastava, Parthib Banerjee +1
Accurate estimation of propagation characteristics of coronal mass ejections (CMEs) is crucial for predicting their geoeffectiveness. Stereoscopic techniques to study the kinematic…
Inflated hot Jupiters: Inferring average atmospheric velocity via Ohmic models coupled with internal dynamo evolution
Daniele Viganò, Soumya Sengupta, Clà udia Soriano-Guerrero +4
The inflated radii observed in hundreds of hot Jupiters (HJ) represent a long-standing open issue. In this study, we quantitatively investigate this phenomenon within the framework…
On The Influence Of The Solar Wind On The Propagation Of Earth-impacting Coronal Mass Ejections
Sandeep Kumar, Nandita Srivastava, Nat Gopalswamy +1
Coronal Mass Ejections (CMEs) are subject to changes in their direction of propagation, tilt, and other properties as they interact with the variable solar wind. We investigated th…
