Scalar field with nonminimal couplings to metric-affine geometry
Ilaria Andrei, Damianos Iosifidis, Laur Järv +1
We study a scalar field nonminimally coupled to metric-affine gravity within actions linear in the affine curvature and containing all independent parity-even and parity-odd terms…
Temperature effects on white dwarfs in modified gravity
Sofía Vidal, Aneta Wojnar, Laur Järv
In this article we analyze the effects of a finite temperature equation of state on the equilibrium structure of white dwarfs in massive Brans-Dicke theory as well as the symmetron…
Inflation with Nieh-Yan-like terms in metric-affine gravity
Ilaria Andrei, Christian Dioguardi, Damianos Iosifidis +3
We study single-field slow-roll inflation in metric-affine gravity with a scalar field non-minimally coupled to the non-Riemannian Ricci scalar and to the divergences of the torsio…
Crystallized white dwarf stars in scalar-tensor gravity
Sofía Vidal, Aneta Wojnar, Laur Järv +1
We study the effects of massive scalar-tensor theories on the internal properties, crystallization, and cooling process of white dwarf stars that might potentially solve observatio…
Exploring the stability of cosmology near general relativity limit with different connections
María-José Guzmán, Laur Järv, Laxmipriya Pati
In this work, we study cosmological spacetime configurations in gravity with nonvanishing symmetric teleparallel connections. It is known that the spatially flat, homogeneou…
