Spontaneous scalarization of neutron stars in teleparallel gravity with derivative torsional coupling
Youcef Kehal, Khireddine Nouicer
We study neutron star configurations in a teleparallel gravity model featuring a scalar field coupled to both matter and torsion. In the Einstein frame, the theory includes a deriv…

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 c…

Alleviating the and tensions in the interacting cubic covariant Galileon model
Sihem zabat, Youcef Kehal, Khireddine Nouicer
The interaction between dark matter and dark energy has become a focal point in contemporary cosmological research, particularly in addressing current cosmological tensions. This s…
