Neutron stars in gravity with conserved energy-momentum tensor: Hydrostatic equilibrium and asteroseismology
Juan M. Z. Pretel, Sergio E. Jorás, Ribamar R. R. Reis +1
We investigate the equilibrium and radial stability of spherically symmetric relativistic stars, considering a polytropic equation of state (EoS), within the framework of …
Fluid pulsation modes from strange stars in a higher-dimensional space-time
José D. V. Arbañil, César H. Lenzi, Manuel Malheiro
In this work, we make the first step to derive non-radial pulsation equations in extra dimensions and investigate how the - and -mode frequencies of strange quark stars, wi…
Stable relativistic polytropic objects with cosmological constant
José D. V. Arbañil, Pedro H. R. S. Moraes
The effects of the cosmological constant on the static equilibrium configurations and stability against small radial perturbations of relativistic polytropic spheres are investigat…
Gravastar model in Randall-Sundrum braneworld
José D V Arbañil, Pedro H R S Moraes, Manuel Malheiro
In this work we derive a gravastar model in Randall-Sundrum II braneworld scenario. Gravastars (or gravitationally vacuum stars) were proposed by Mazur and Mottola as systems of gr…
Extra dimensions' influence on the equilibrium and radial stability of strange quark stars
José D. V. Arbañil, Geanderson A. Carvalho, Ronaldo V. Lobato +2
We analyze the influence of extra dimensions on the static equilibrium configurations and stability against radial perturbations. For this purpose, we solve stellar structure equat…
Compact Astrophysical Objects in gravity
P. H. R. S. Moraes, J. D. V. Arbañil, G. A. Carvalho +4
In this article we study the hydrostatic equilibrium configuration of neutron stars (NSs) and strange stars (SSs), whose fluid pressure is computed from the equations of state $p=ω…
