“…It is worthwhile to mention here that the range of physical quantities in EMSG increases and provides more viable as well as stable compact stars as compared to GR [
19,60,62 ] and other modified theories. [
39–46 ] For example, in
theory, it is found that physical quantities such as effective matter variables, energy conditions, EoS parameters and speed of sound are satisfied for very small range and the compact star Her X‐1 under the effects of the second gravity model does not remain stable. [
39 ] In
theory, the evolution of compact stars (SAXJ1808.4‐3658 and 4U1820‐30) are supported by all three gravity models while for HerX ‐ 1, there are some restrictions asserted by the second model to be completely physically viable.…”
