Neutron Stars in Scalar Torsion Theories with Nonminimal Coupling
Youcef Kehal, Khireddine Nouicer, Hamza Boumaza
We study the existence and structure of static and slowly rotating neutron stars (NSs) in a particular truncation of scalar torsion theory with a scalar field non-minimally co…

Axial and polar stability of neutron stars in scalar-tensor theories with disformal coupling
Hamza Boumaza
In the present work, we study the radial and non-radial perturbative stability of neutron stars in which the matter is disformally coupled to the metric. First, we derive the gravi…
