چکیده

This paper aims to investigate the existence and properties of anisotropic quark stars in context self-interacting Brans–Dicke theory. In this theory, gravitational constant general relativity is replaced by a dynamical massive scalar field accompanied potential function. Researchers believe that strange may evolve from neutron when neutrons fail endure extreme temperature pressure interior region. As consequence, they breakdown into their constituent particles, known as quarks. order construct well-behaved star model under influence field, we formulate equations employing MIT bag model. The (strange matter equation state) most suitable choice for it has successfully described compactness certain stellar bodies. Furthermore, estimates mass based on data cosmic events GW170817 GW190425 support developed considering three types matter: strange, up, down. involved differentiates between false true vacuum. We consider static sphere with fluid employ observed masses radii candidates (RXJ 1856-37 PSR J1614-2230) matching conditions at boundary evaluate value constant. Further, impact state parameters viability (via energy conditions) well stability (through speed sound constraints) self-gravitating objects. It found obtained values lie within accepted range (58.9 MeV/fm3 ≤ B 91.5 MeV/fm3). Moreover, structure meets necessary criteria.

Wiggly Strings in Linearized Brans-dicke Gravity

The metric around a wiggly cosmic string is calculated in the linear approximation of Brans-Dicke theory of gravitation. The equations of motion for relativistic and nonrelativistic particles in this metric are obtained. Light propagation is also studied and it is shown that photon trajectories can be bounded.

Renormalization in quantum Brans-Dicke gravity

In the Brans-Dicke model we treat the scalar field exactly and expand the gravitational field in a power series. A comparison with 2D sigma models and φ perturbation theory in four dimensions suggests that the perturbation series in 4D Brans-Dicke model is renormalizable.

Illusions of general relativity in Brans–Dicke gravity

Contrary to common belief, the standard tenet of Brans–Dicke theory reducing to general relativity in the ω → ∞ limit is false when the trace of the matter energy–momentum tensor vanishes. The issue is clarified in a new approach using conformal transformations. The otherwise unaccountable limiting behavior of Brans–Dicke gravity is easily understood in terms of the conformal invariance of the ...

Neutrino Oscillations in Brans–Dicke Theory of Gravity

Flavor oscillations of neutrinos are analyzed in the framework of Brans–Dicke theory of gravity. We find a shift of quantum mechanical phase of neutrino proportional to GN∆m and depending on the parameter ω. Consequences on atmospheric, solar and astrophysical neutrinos are discussed.

Mass Definitions for Boson Stars in Brans Dicke Gravity

We consider boson stars in Brans Dicke gravity, focusing on general ω weak field solutions and ω = −1 strong field solutions. We discuss three definitions of quasilocal mass adapted to the spherical symmetry of the solutions: the Schwarzschild mass, the Keplerian mass and the Tensor mass, and discuss how the asymptotic values of these masses may be derived from an ADM-like formula. We show that...
