Query: Tidal Love numbers of neutron stars in Rastall gravity   Gravitational-wave measurements of the tidal deformability of neutron stars
could reveal important information regarding their internal structure, the
equation of state of high-dense nuclear matter and gravity in strong field
regime. In this work, we extend the relativistic theory of the tidal
deformability of neutron stars to Rastall gravity. Both the electric-type and
magnetic-type quadrupole tidal Love numbers are calculated for neutron stars in
the polytrope model. It is found that neutron star's tidal Love numbers in
Rastall gravity is significantly smaller than those in general relativity. Our
results provide new evidence of the degeneracy between the modification of
gravity and the equation of state of nuclear matter in neutron stars.
