Time evolution of accreting magnetofluid around a compact object-Newtonian analysis
Time evolution of a thick disc with finite conductivity around a nonrotating compact object is presented. Along with the Maxwell equations and the Ohm's law, the Newtonian limit of the relativisticExpand

Observations, light curves analysis and pulsation behavior of the Algol-type eclipsing binary system XX Cep
Abstract We present the long term photometric variations of the classical Algol type binary XX Cep with a δ Scuti type pulsating component. Modeling of the system shows that the secondary componentExpand

Self‐similar evolutionary solutions for an accreting magneto‐fluid around a compact object with finite electrical conductivity
In this paper, we investigate the time evolution of an accreting magneto-fluid with finite conductivity. For the case of a thin disk, the fluid equations along with Maxwell's equations are derived inExpand

Radial Velocity and Light Curves Analysis of the Contact Binary V1073 Cygni
In this study complete BV light curves of the W Ursae Majoris binary V1073 Cygni obtained in 2005 are presented. We have used the spectroscopic data of V1073 Cyg obtained by Ahn et al. (1992) forExpand

The Effect of Dark Matter on Stars at the Galactic Center: The Paradox of Youth Problem
Stars that evolve near the Galactic massive black hole show strange behaviors. The spectroscopic features of these stars show that they must be old. But their luminosities are much higher than theExpand

Cosmological constrains on new generalized Chaplygin gas model
We use different combinations of data samples to investigate the new generalized Chaplygin gas (NGCG) model in the context of dark energy (DE) cosmology. Using the available cosmological data, we putExpand

Period change of binary pulsars due to the accretion of dark matter particles
As binary systems move inside galaxies, they interact with the dark matter halo. This interaction leads to the accretion of dark matter particles inside binary components. The accretion of darkExpand
