The understanding of stellar structure represents the crossroads of our theories of the
nuclear force and the gravitational interaction under the most extreme conditions observably …

The dawn of the twenty-first century came with very positive prospects for gravity, cosmology,
and astrophysics. Technological progress made it possible for cosmology to enter to its …

One century after its formulation, Einstein's general relativity (GR) has made remarkable
predictions and turned out to be compatible with all experimental tests. Most of these tests …

In this work, we study the neutron star phenomenology of R p attractor theories in the
Einstein frame. The Einstein frame R p attractor theories have the attractor property that they …

Scalarization is a mechanism that endows strongly self-gravitating bodies, such as neutron
stars and black holes, with a scalar-field configuration. It resembles a phase transition in that …

Astrophysical black hole candidates are thought to be the Kerr black holes of general
relativity, but there is not yet direct observational evidence that the spacetime geometry …

In this work we study static neutron stars in the context of several inflationary models which
are popular in cosmology. These inflationary models are nonminimally coupled scalar …

Exploring the nature of gravity in the strong curvature regime is seeing a surge of interest
lately. This is expected to intensify, as it is driven by current and future observations of …

This study focuses on the static neutron star perspective for two types of cosmological
inflationary attractor theories, namely the induced inflationary attractors and the quadratic …
