We aim at deriving accurate atmospheric parameters and chemical abundances of 19 barium(Ba) stars, including both strong and mild Ba stars, based on the high si
Following the theory of relativity, in the presence of an ultrastrong magnetic field (UMF) and utilizing a nuclear shell model, we carry out an estimation of th
When observing blazars, we identified a new eclipsing binary named GSC03517–00663. The light curves of GSC 03517–00663 are typical of EW-type light curves. Ba
We use a composite gravitational galactic model consisting of a disk,a halo, a massive nucleus and a strong nuclear bar,in order to study the connections betwee
