Abstract

This work is focused on the identification of cracking points in charged spherically symmetric stellar configurations in the vicinity of f(R) gravitational theory. To identify cracking points, the hydrostatic equilibrium equation is for the application of local density perturbation scheme. We apply local density perturbation technique to test the viability of 4U 1820-30, Vela X-1, and SAX J1808.4-3658 according to different physical parameters involved in model presented by Nazar and Abbas (Adv Astron 2021:6698208, 2021). It is concluded through graphical illustrations that cracking points help in the refinement of the stability regions by exhibiting cracking in different interior regions.

期刊介绍: The aims of this peer-reviewed online journal are to distribute and archive all relevant material required to document, assess, validate and reconstruct in detail the body of knowledge in the physical and related sciences. The scope of EPJ Plus encompasses a broad landscape of fields and disciplines in the physical and related sciences - such as covered by the topical EPJ journals and with the explicit addition of geophysics, astrophysics, general relativity and cosmology, mathematical and quantum physics, classical and fluid mechanics, accelerator and medical physics, as well as physics techniques applied to any other topics, including energy, environment and cultural heritage.
