Tidal Deformability of Neutron Stars in Unimodular Gravity
read the original abstract
Unimodular gravity is a modified theory with respect to general relativity by an extra condition that the determinant of the metric is fixed. Especially, if the energy-momentum tensor is not imposed to be conserved separately, a new geometric structure appears with potentially observational signatures. In this paper, we study tidal deformability of compact star in the unimodular gravity under the assumption of non-conserved energy-momentum tensor. Both the electric-type and magnetic-type quadrupole tidal Love numbers are calculated for neutron stars with polytrope model. It is found that the electric-type tidal Love numbers are monotonically increasing, but the magnetic-type ones are decreasing, with the increase of the non-conservation parameter. Compared with the observational data from detected gravitational-wave events, a small negative non-conservation parameter is favored.

Tidal Love numbers of multi-state Boson stars
Quadrupolar electric tidal Love numbers of multi-state boson stars flip from positive to negative when mu~1 > 0.891 or omega~0 > 0.777, while magnetic Love numbers stay negative.
