Note on the charged boson stars with torsion-coupled field
Dubravko Horvat, Sasa Ilijic, Anamarija Kirin +1
Within the framework of the extended teleparallel gravity, a new class of boson stars has recently been constructed by introducing the nonminimal coupling of the scalar field to th…
Nonminimally coupled scalar field in teleparallel gravity: boson stars
Dubravko Horvat, Sasa Ilijic, Anamarija Kirin +1
We study the nonminimally coupled complex scalar field within the framework of teleparallel gravity. Coupling of the field nonminimally to the torsion scalar destroys the Lorentz i…
Formation of photon spheres in boson stars with a nonminimally coupled field
Dubravko Horvat, Sasa Ilijic, Anamarija Kirin +1
A static, spherically symmetric, asymptotically flat spacetime may allow for circular, closed null-geodesics which are said to belong to a photon sphere. In the context of gravitat…
Dark energy-like stars from nonminimally coupled scalar field
Dubravko Horvat, Anja Marunovic
We show that even a rather minimal extension of the Einstein - Hilbert action by a nonminimal coupling of the scalar field to the Ricci curvature scalar results in configurations t…
On Wormhole Throats in Gravity Theory
Andrew DeBenedictis, Dubravko Horvat
We study the existence and properties of wormhole throats in modified gravity theory. Specifically, we concentrate on the cases where the lapse is not necessarily constant,…
Radial stability analysis of the continuous pressure gravastar
Dubravko Horvat, Sasa Ilijic, Anja Marunovic
Radial stability of the continuous pressure gravastar is studied using the conventional Chandrasekhar method. The equation of state for the static gravastar solutions is derived an…
