An analytical anisotropic compact stellar model of embedding class I

نویسندگان

چکیده

A class of solutions Einstein field equations satisfying Karmarkar embedding condition is presented which could describe static, spherical fluid configurations, and serve as models for compact stars. The under consideration has unequal principal stresses i.e. locally anisotropic. certain physically motivated geometry metric potential been chosen codependency the potentials outlines formation model. exterior spacetime assumed described by Schwarzschild solution. smooth matching interior to across boundary that radial pressure zero lead us determine model parameters. Physical requirements stability analysis demanded a realistic star are satisfied. developed investigated graphically exploring data from some known objects. mass-radius (M-R) relationship shows maximum mass admissible observed pulsars given surface density also investigated. Moreover, physical profile moment inertia (I) thus obtained confirmed Bejger–Haensel concept.

Embedding Compact Strongly Pseudoconvex Cr Manifolds of Class C

In this paper we derive maximal pointwise Hölder estimates for the Kohn’s Laplacian on strongly pseudoconvex CR manifolds of class C3 using the Tanaka-Webster Pseudohermitian metric. The estimates can be used to improve the Boutet De Monvel’s embedding theorem for strongly pseudoconvex compact CR manifolds of real dimension greater or equal to five with less smoothness assumption.

Ultra - compact dwarf galaxies : a new class of compact stellar system discovered in the Fornax Cluster

We have used the 2dF spectrograph on the Anglo-Australian Telescope to obtain a complete spectroscopic sample of all objects in the magnitude range, 16.5 < bJ < 19.8, regardless of morphology, in an area centred on the Fornax Cluster of galaxies. Among the unresolved targets are five objects which are members of the Fornax Cluster. They are extremely compact stellar systems with scale lengths l...

An Anisotropic Illumination Model of Seyfert I Galaxies

We present a new model of accretion disk where the disk luminosity is entirely due to the reprocessing of hard radiation impinging on the disk. The hard radiation itself is emitted by a hot point source above the disk, that could be physically realized by a strong shock terminating an aborted jet. This hot source contains ultra-relativistic leptons scattering the disk soft photons by Inverse Co...

Stellar and Circumstellar Properties of Class I Protostars

We present a study of the stellar and circumstellar properties of Class I sources using low-resolution (R∼1000) near-infrared Kand L-band spectroscopy. We measure prominent spectral lines and features in 8 objects and use fits to standard star spectra to determine spectral types, visual extinctions, K-band excesses, and water ice optical depths. Four of the seven systems studied are close binar...
