Fate of Electromagnetic Field on the Cracking of PSR J1614-2230 in Quadratic Regime

Abstract EN

We study the cracking of compact object PSRJ1614-2230 in quadratic regime with electromagnetic field.

For thispurpose, we develop a general formalism to determine the cracking ofcharged compact objects.

We apply local density perturbations tohydrostatic equilibrium equation as well as physical variablesinvolved in the model.

We plot the force distribution functionagainst radius of the star with different parametric values of modelboth with and without charge.

It is found that PSR J1614-2230remains stable (no cracking) corresponding to different values ofparameters when charge is zero, while it exhibits cracking (unstable)when charge is introduced.

We conclude that stability regionincreases as amount of charge increases.
