Possible Existence of Dark Matter Admixed Pulsar in M31 and M87 Galaxies
Sulagna Mondal, Sajahan Molla, Prabir Kumar Halder +1
In previous studies [1, 2, 3] the possible existence dark matter admixed pulsar have been discussed based on three different dark matter density profiles, Singular Isothermal Spher…
Analytical model on mass limit of strange stars
Sajahan Molla, Masum Murshid, Mehedi Kalam
In this paper, we present a new kind of stellar model using the Nariai IV metric. This model can be used to study the strange/quark stars(which is our present interest, though it c…
Analytical model of Strange star in Durgapal spacetime
Rabiul Islam, Sajahan Molla, Mehedi Kalam
A new strange star model based on Durgapal IV metric (Durgapal 1982) is presented here.Here we have applied a specific method to study the inner physical properties of the compact…
Analytical model of millisecond pulsar PSR J0514-4002A
Sajahan Molla, Bidisha Ghosh, Mehedi Kalam
We construct a relativistic model for the newly discovered millisecond pulsar PSR J0514 - 4002A located in the globular cluster NGC 1851 (A. Ridolfi, P.C.C. Freire, Y. Gupta, S.M.…
Does Dark Matter admixed pulsar exist ?
Sajahan Molla, Bidisha Ghosh, Mehedi Kalam
In this paper, we have considered a twofluid model assuming that the pulsars are made of ordinary matter admixed with dark matter.Contribution of dark matter comes from the fitting…
Analytical model of compact star in low-mass X-ray binary with de Sitter spacetime
Sajahan Molla, Rabiul Islam, Md. Abdul Kayum Jafry +1
In this article, we introduce a de-sitter model in favor of compact stars in low-mass X-ray binary. Here, we merge the presence of the cosmological constant on a small scale to dis…
Neutron Stars : A Comparative Study
Mehedi Kalam, Sk. Monowar Hossein, Sajahan Molla
The inner structure of neutron star is considered from theoretical point of view and is compared with the observed data. We have proposed a form of an equation of state relating pr…
Isotropic star in low-mass X-ray binaries and X-ray pulsars
Mehedi Kalam, Sk. Monowar Hossein, Sajahan Molla
We present a model for compact stars in the low mass X-ray binaries(LMXBs) and X-ray pulsars using a metric given by John J. Matese and Patrick G. Whitman \citep{Matese and Whitman…
Compact Stars in low-mass X-ray binaries
Sk. Monowar Hossein, Sajahan Molla, Md. Abdul Kayum Jafry +1
We propose a model for compact stars in low-mass X-ray binaries(LMXBs) namely KS 1731-260, EXO 1745-248 and 4U 1608-52. Here we investigate the physical phenomena of a compact star…
Analytical model of strange star in the low-mass X-ray binary 4U 1820-30
Mehedi Kalam, Farook Rahaman, Sajahan Molla +2
In this article, we have proposed a model for a realistic strange star under Tolman VII metric\citep{Tolman1939}. Here the field equations are reduced to a system of three algebrai…
Anisotropic Quintessence stars
Mehedi Kalam, Farook Rahaman, Sajahan Molla +1
We propose a relativistic model for quintessence stars with the combination of an anisotropic pressure corresponding to normal matter and a quintessence dark energy having a charac…
