The objective of this work is to examine the enhancement of thermal energy transfer in Ellis
THNF (tetra hybrid nanofluid) flow with magnetic dipole permits on a vertical surface. Using …

The process of the Sun's polar field cancellation reversal commences with the emergence of
new cycle Hale's polarity active regions. Once the Sun undergoes polarity reversal, typically …

The solar cycle is generated by a magnetohydrodynamic dynamo mechanism which
involves the induction and recycling of the toroidal and poloidal components of the Sun's …

Prediction of the amplitude of solar cycle is important for understanding the mechanism of
solar cycle and solar activity influence on space-weather. We analysed the combined data of …

Forecasting the amplitude and timing of the sunspot cycle is highly important for solar
physics and space weather applications, but high-precision prediction of solar magnetic …

Predicting solar activity changes is crucial for Earth's climate, communication systems, and
aerospace technology. This study employs the Long Short-Term Memory Fully …

The Ludendorff coronal flattening index is a quantitative parameter to analyze the global
structure and shape of the corona. This index plays a crucial role in identifying solar …

1. Background The IAU Commission E1 “Solar Radiation and Structure”(CE1) covers
observational and theoretical aspects of the Sun's radiation, structure, and variability under …

This paper aims to develop a reliable mathematical model for predicting sunspot
characteristics and their impact on various fields. Previous studies have used methods such …
