In this paper, we introduce the cigar- shaped metric . Such metric can be obtained by the Schwarzschild black hole. Here, we write the Dirac equation in the corresponding background. We take some change of variable for the ...

In this study, researchers investigated the properties of oscillated and non-oscillated bright points (BPs) in different regions of the Sun, including active regions (ARs) and coronal holes (CHs). The findings revealed ...

In this paper, we investigate the effect of solar corona magnetic activities during 11-year periods and energetic particles on global warming. According to atmospheric changes during the past years, the relationship between ...
