Exploring Gravastar‐Like Structures with Strongly Interacting Quark Matter Shell in the Framework of <i>f(Q)</i> Gravity Under Conformal Symmetry

Abstract In this work, gravastars‐like structures are investigated in spherically symmetric and static space‐time within the gravity framework, coupled with conformal symmetry. The conventional gravastar model is modified by introducing a strongly interacting quark matter shell, which maintains the apex of causal limit through the EoS, , where, is the bag constant. Non‐singular and non‐vanishing solutions for the interior and shell regions are obtained, respectively. The Israel junction condition is used to evaluate the mass of the thin shell for different choices of characteristic radii. Interestingly, the mass of the shell is independent of the matter distribution in the shell region. For radii 9.009, 10.009, and 11.009 Km, the mass increases to , and , respectively. The physical features associated with the gravastars, such as, proper length, energy, and entropy of the shell region are studied within the parameter space. Surface redshift calculations were used to validate the proposed model.
