Numerical Approach to the Exterior Solution of Spherically Symmetric and Static Configuration in Scalar-Tensor Theories
A. Savaş Arapoğlu, Sermet Çağan, A. Emrah Yükselci
We numerically examine the exterior solution of spherically symmetric and static configuration in scalar-tensor theories by using the nonminimally coupled scalar field with zero po…
The Effect of Non-minimally Coupled Scalar Field on Gravitational Waves from First-order Vacuum Phase Transitions
A. Savaş Arapoğlu, A. Emrah Yükselci
We investigate first-order vacuum phase transitions in the presence of a non-minimally coupled scalar field starting with the coupling effect on the initial dynamics of phase trans…
A Neutron Star with a Strange Quark Star-like Mass-Radius Relation
A. Savaş Arapoğlu, A. Emrah Yükselci
We study the structure of spherically symmetric and static objects in the presence of a nonminimally coupled scalar field having a potential of the form . We…
Dynamical System Analysis of a Five-Dimensional Cosmological Model
A. Savaş Arapoğlu, Ezgi Canay, A. Emrah Yükselci
A five-dimensional cosmological model including a single perfect fluid is studied in the framework of dynamical system analysis. All the critical points of the system with their st…
