Covariant phase space analysis of static spherical vacua in power-law gravity
Mariam Campbell, Eduardo Bittencourt, Peter K. S. Dunsby
We formulate the static, spherically symmetric vacuum equations of power-law metric gravity as a covariant autonomous system using the formalism. The finite critic…
Covariant Tolman-Oppenheimer-Volkoff equations in Energy-Momentum Squared Gravity
Eduardo Bittencourt, Mariam Campbell, Peter K. S. Dunsby +1
We study static, spherically symmetric stellar configurations in an extended class of Energy--Momentum Squared Gravity using the covariant \(1+1+2\) semi-tetrad formalism. For perf…
Covariant Dynamical Systems Formulation of the Tolman-Oppenheimer-Volkoff Equations
Eduardo Bittencourt, Mariam Campbell, Peter K. S. Dunsby +1
We revisit static, spherically symmetric perfect-fluid stellar models in General Relativity within the framework of the semi-tetrad formalism. For locally rotationally symm…
Bouncing cosmologies in the presence of a Dirac-Born-Infeld field
Mariam Campbell, Richard Daniel, Peter K. S. Dunsby +1
We perform a detailed dynamical system analysis for the behaviour of a Dirac-Born-Infeld (DBI) field in a spatially closed Friedmann-Lemaître-Robertson-Walker (FLRW) cosmology. The…
Some exact relativistic star solutions in gravity
Mariam Campbell, Sante Carloni, Peter K. S. Dunsby +1
We present a covariant description of non-vacuum static spherically symmetric spacetimes in gravity applying the (1+1+2) covariant formalism. The propagation equations are t…
