We present the physical and geometrical parameters of the individual components of the close visual double-lined spectroscopic binary system Gliese 762.1, which
We study the interaction between dark energy(DE) and dark matter in the scope of anisotropic Bianchi type-I space-time. First we derive the general form of the
Using a large sample of blazars of the Fermi observations presented by Abdo et al.,we constructed a sample of blazars including high energy peaked BL Lac object
The fact that a fermion system in an external magnetic field breaks the spherical symmetry suggests that its intrinsic geometry is axisymmetric rather than sphe
Recently,the magnetar Swift J1834.9—0846 has been reported to have a possible wind nebula.It is shown that both the magnetar and its wind nebula are understand
