Equilibrium and stability of relativistic stars in extended theories of gravity

Now, there is the correct day of this seminar - FRIDAY as usual! :-) The static, spherically symmetric equilibrium configurations in extended theories of gravity (ETGs) is studied. We show that the stellar structure in ETGs can be recast in a very generic form: i.e. one gets the generalization of the Tolman-Oppenheimer-Volkoff equations. A stability analysis is also performed with special focus on the particular example of scalar-tensor gravity.
