Strange stars in the framework of higher curvature gravity

Understand

We study the influence of higher curvature effects on stellar structure and conclude that the properties of stars are greatly impacted when such terms are dynamic.

• In particular the surface gravitational redshift which is connected to the equation of state and also the mass-radius ratio differs greatly from the corresponding values in general relativity as evidenced through our empirical comparisons.
• A model of a superdense star with strange star equation of state is constructed within the framework of the Einstein--Gauss--Bonnet theory.
• Under these assumptions large classes of solutions are admitted by the field equations.
