Anisotropic compact stars: Constraining model parameters to account for physical features of tidal Love numbers

نویسندگان

چکیده

In this paper, we develop a new class of models for compact star with anisotropic stresses inside the matter distribution. By assuming linear equation state composition solve Einstein field equations. our approach, interior solutions use particular form ansatz metric function $g_{rr}$. The exterior solution is assumed as Schwarzschild and joined obtained across boundary star. These matching metrices along condition vanishing radial pressure at lead us to determine model parameters. physical acceptability has verified by making current estimated data available from pulsar 4U1608-52. Thereafter, anisotropy due tidal effects calculate Love numbers compare results observed stars, viz. KS 1731- 260,4U 1608- 52,4U 1724- 207,4U 1820- 30,SAX J1748.9-2021 EXO 1745-268. overall situation confirms viability proposed approach,which can shed light on relativistic objects.

Tidal Love numbers of neutron stars

For a variety of fully relativistic polytropic neutron star models we calculate the star’s tidal Love number k2. Most realistic equations of state for neutron stars can be approximated as a polytrope with an effective index n ≈ 0.5 − 1.0. The equilibrium stellar model is obtained by numerical integration of the Tolman-Oppenheimer-Volkhov equations. We calculate the linear l = 2 static perturbat...

Interior structure models and tidal Love numbers of Titan

[1] Interior models of a differentiated Titan with an internal ammonia-water ocean and chondritic radiogenic heat production in an undifferentiated rock + iron core have been calculated. We assume thermal and mechanical equilibrium and calculate the structure of the interior as a function of the thickness of an ice I layer on top of the ocean as well as the moment of inertia factor and the tida...

Constraining tidal dissipation in F-type main-sequence stars: the case of CoRoT-11

Context. Tidal dissipation in late-type stars is presently poorly understood and the study of planetary systems hosting hot Jupiters can provide new observational constraints to test proposed theories. Aims. We focus on systems with F-type main-sequence stars and find that the recently discovered system CoRoT-11 is presently the best suited for this kind of investigation. Methods. A classic con...

Tidal deformation of Ganymede: Sensitivity of Love numbers on the interior structure

Tidal deformation of icy satellites provides crucial information on their subsurface structures. In this study, we investigate the parameter dependence of the tidal displacement and potential Love numbers (i.e., h2 and k2, respectively) of Ganymede. Our results indicate that Love numbers for Ganymede models without a subsurface ocean are not necessarily smaller than those with a subsurface ocea...
