Abstract:
The common picture of the Universe is that it is made up of spherical or
approximately spherical stellar objects immersed in vacuum. These spacetime
objects produce gravitational fields that are approximately spherically
symmetric and can be represented as spherically symmetric solutions to the
gravitational field equations. We investigate the problem of spherically
symmetric spacetimes in the context of modified gravity and in particular
we focus on f(R) theories of gravity.
