  We discuss masses, radii, and tidal deformabilities of neutron stars
constructed from the holographic Witten-Sakai-Sugimoto model. Using the same
model for crust and core of the star, we combine our theoretical results with
the latest astrophysical data, thus deriving more stringent constraints than
given by the data alone. For instance, our calculation predicts -- independent
of the model parameters -- an upper limit for the maximal mass of the star of
about 2.46 solar masses and a lower limit of the (dimensionless) tidal
deformability of a 1.4-solar-mass star of about 277.
