Quartic time-dependent oscillatons
Abstract
In this paper, we will study some properties of oscillaton, spherically symmetric object made of a real time-dependent scalar field, Using a self- interaction quartic scalar potential instead of a quadratic or exponential ones discussed in previous works. Since the oscillatons can be regarded as models for astrophysical objects which play the role of dark matter, there- fore investigation of their properties has more importance place in present time of physics; research. Therefore we investigate the properties of these objects by Solving the system of differential equations obtained from the Einstein Klein Gordon (EKG) equations and will show their importance as new candidates for the role of dark matter in the galactic scales.
