X-ray pulsed light curves of highly compact neutron stars as probes of scalar-tensor theories of gravity
Tulio Ottoni, Jaziel G. Coelho, Rafael C. R. de Lima +2
The strong gravitational potential of neutron stars (NSs) makes them ideal astrophysical objects for testing extreme gravity phenomena. We explore the potential of NS X-ray pulsed…
Impact of stratified rotation on the moment of inertia of neutron stars
Jonas P. Pereira, Tulio Ottoni, Jaziel G. Coelho +2
Rigid (Uniform) rotation is usually assumed when investigating the properties of mature neutron stars (NSs). Although it simplifies their description, it is an assumption because w…
Stellar structure in a Newtonian theory with variable
Júlio C. Fabris, Túlio Ottoni, Júnior D. Toniato +1
A Newtonian-like theory inspired by the Brans-Dicke gravitational Lagrangian has been recently proposed. For static configurations the gravitational coupling acquires an intrinsic…
Scalar charges and pulsar-timing observables in the presence of nonminimally coupled scalar fields
Raissa F. P. Mendes, Tulio Ottoni
Pulsar-timing has become a celebrated tool for probing modifications to General Relativity in the strong-field surroundings of neutron stars. Here we investigate whether scalar-ten…
