Overturning and cracking of stellar objects in modified $$f(R, \varphi )$$ f ( R , φ ) gravity by Adnan Malik, Attiya Shafaq, Fatemah Mofarreh, M. Farasat Shamir, Wedad Albalawi

“…It is concluded that cracking points appear in the different interior regions of these three stars. Significantly, this study illustrates the effectiveness of the cracking approach by highlighting the regions sensitive to localized density disruptions, offering valuable insights into the structural behavior of compact stars within a modified gravity framework.…”
