EDITORIAL NOTE

I am delighted to introduce a scientific journal being published by the Department of Physics, University of North Bengal, Journal of Physics Research and Education (JPRE), a new journal that emphasizes contribution in the emerging areas of research and education in Physics. JPRE provides a really exciting opportunity to consider the truly interdisciplinary nature of research in Physics at a time of great change across the wider landscape of Physics research. The objective of JPRE is to publish up-to-date, high-quality and original research papers alongside relevant and insightful reviews. The journal is also dedicated to maintaining and improving the standard of taught Physics in Universities and the submitted articles will be peer-reviewed. The journal aspires to be vibrant, engaging and accessible, and at the same time it should address the frontier, integrative and challenging issues in Physics. All articles must therefore contain contents that are physics research in interdisciplinary nature and applicable to the teaching of Physics at University level. Needless to say, any papers that you wish to submit, either individually or collaboratively, are much appreciated and will make a substantial contribution towards the advancement and success of the journal. Best wishes and thank you in advance for your contribution to the Journal of Physics Research and Education.

    Relativistic compact stellar model describing anisotropic stars
    (University of North Bengal, 2021-02) Baskey, Lipi; Das, Shyam
    In this paper, we have derived a class of analytical solutions of Einstein field equations for a spherically symmetric anisotropic matter distribution. By choosing one of the metric potentials grr to be Krori-Barua metric type and a specific choice of anisotropy we obtain the other metric function. The interior solutions thus obtained has been utilized to construct a potentially stable model that could describe compact stellar objects. The exterior vacuum region has been assigned with the Schwarzschild spacetime metric. Across the boundary of the compact star where the radial pressure drops to zero, the interior metric has been matched smoothly with the exterior metric to fix the model parameters associated with the solutions. All the regularity conditions, energy conditions and all other physical requirements demanded for a realistic compact system has been shown to satisfy graphically with this model corresponding to the pulsars 4U1820 - 30 (Mass= l.58M0 and radius= 9.1 km) [1] and Gen X - 3 (Mass= l.49M0 and radius= 10.136 km)[2]. The stability of the model is also discussed using some of the known stability criterion namely TOV equation, adiabatic index, Buchdahl condition and Herrera's cracking concept etc. The wide applicability of our developed model has been justified with the numerical values of current observational data set from various other known compact stars to a high degree of accuracy.
