Context. To constrain Randall-Sundrum type braneworld gravity models and the expected rapid evaporation of astrophysical black holes due to the emission of gravitational modes in the extra dimension. Aims. It is argued that the black-hole X-ray binary XTE J1118+480 is suitable for a constraint on the asymptotic curvature radius of the extra dimension in such braneworld models. An upper limit on...

The main properties of the logamediate inflation driven by a non-canonical scalar field in framework DGP braneworld gravity are investigated. Considering high energy conditions we calculate slow-roll parameters, analytically. Then, deal with perturbation theory and most important respective parameters such as spectral index tensor-to-scalar ratio. We find that spectrum fluctuations is always re...

We study the properties of gravity and bulk fields living in a torsion warped braneworld. The is driven by background vector whose norm provides source for cosmological constant. For as derivative scalar field, we find new isotropic anisotropic thick brane geometries. analyse features bosonic fermionic this standing wave scenarios. nonminimal coupling between field geometry leading to modificat...

We consider the double pulsar PSR J0737-3039A/B binary system as a laboratory to locally test the orbital effects induced by an uniform cosmological constant Λ in the framework of the known general relativistic laws of gravity, and the DGP braneworld model of gravity independently of the cosmological acceleration itself for which they were introduced. We, first, construct the ratio R = ∆ω̇/∆P of...

Considering an energy density of the form [Formula: see text] (where is arbitrary positive constant with dimension and text]), a shape function obtained by using field equations braneworld gravity theory in this paper. Under isotropic scenario wormhole solutions are considering six different redshift functions along new function. For anisotropic case, under consideration five text], where const...

Braneworld cosmology has several attractive and distinctive features. For instance the effective equation of state in braneworld models can be both quintessence-like (w0 ≥ −1) as well as phantomlike (w0 ≤ −1). Models with w0 ≥ −1 (w0 ≤ −1) are referred to as Brane 2 (Brane 1) and correspond to complementary embeddings of the brane in the bulk. (The equation of state in Brane 1 can successfully ...

Using the generalized procedure proposed by Wu et al23 recently, we construct the first law of thermodynamics on apparent horizon in a general braneworld model with curvature correction terms on the brane and in the bulk, respectively. The explicit entropy formulary of apparent horizon in the general braneworld is worked out. We also discuss the masslike function which associated with a new typ...
