Description
Modified gravity models arise from different motivations but
in cosmology are studied because of
their properties that allow inflation or the current
accelerated expansion.
We have concentrated on the local matter configurations and
compared some modified gravity
model properties to the general relativistic counterparts
and observations.
The studied gravity models are cosmologically motivated
f(R) theories (CDTT and HS) and
a scalar-tensor model class arising the O'Hanlon action.
We have numerically analyzed the physically parametrized
polytropic stellar configurations with the above
models to study their viability.
