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 …

In this review we present a thoroughly comprehensive survey of recent work on modified
theories of gravity and their cosmological consequences. Amongst other things, we cover …

Modified gravity theories have received increased attention lately due to combined
motivation coming from high-energy physics, cosmology, and astrophysics. Among …

We review the recent literature on modified theories of gravity in the Palatini approach. After
discussing the motivations that lead to consider alternatives to Einstein's theory and to treat …

Beyond Einstein's Gravity is a graduate level introduction to extended theories of gravity and
cosmology, including variational principles, the weak-field limit, gravitational waves …

We search for spherically symmetric solutions of f (R) theories of gravity via the Noether
symmetry approach. A general formalism in the metric framework is developed considering …

Spherical symmetry in f (R)-gravity is discussed in detail considering also the relations to the
weak field limit. Exact solutions are obtained for constant Ricci curvature scalar and for Ricci …

Non-vacuum static spherically symmetric solutions in Palatini f (R) gravity are examined. It is
shown that for generic choices of f (R), there are commonly used equations of state for which …

Using a simple model of low-mass stellar objects we have shown modified gravity impact on
their early evolution, such as Hayashi tracks, radiative core development, effective …

A few questions related to white dwarfs' physics is posed. It seems that the modified gravity
framework can be a good starting point to provide alternative explanations to cooling …
