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…
