Using continuous wavelet transform, we examine the relationship between solar activity and the annual precipitation in the Beijing area. The results indicate th
A rare Type I-like noise storm was observed with the solar radio spectrometers (1.0-2.0 GHz and 2.60-3.8 GHz) at National Astronomical Observatories of China (N
The electrostatic potential of electrons near the surface of static strange stars at zero temperature is studied within the frame of the MIT bag model. We find
Based on previous work, we investigate the propagation of CMEs in amore realistic plasma environment than the isothermal atmosphere, and find thatMach number MA
We present an exact analytical solution of the gravitational field equa-tions describing a static spherically symmetric anisotropic quark matter distribution.Th
This paper presents the recent progress in our project of estimating nearreal-time electric fields and currents in the ionosphere through our computer systemcal
