We investigate a simple holographic model for cold and dense deconfined QCDmatter consisting of three quark flavors. Varying the single free parameter ofthe model and utilizing a Chiral Effective Theory equation of state (EoS) fornuclear matter, we find four different compact star solutions: traditionalneutron stars, strange quark stars, as well as two non-standard solutions werefer to as hybrid stars of the second and third kind (HS2 and HS3). The HS2sare composed of a nuclear matter core and a crust made of stable strange quarkmatter, while the HS3s have both a quark mantle and a nuclear crust on top of anuclear matter core. For all types of stars constructed, we determine not onlytheir mass-radius relations, but also tidal deformabilities, Love numbers, aswell as moments of inertia and the mass distribution. We find that there existsa range of parameter values in our model, for which the novel hybrid stars haveproperties in very good agreement with all existing bounds on the stationaryproperties of compact stars. In particular, the tidal deformabilities of thesesolutions are smaller than those of ordinary neutron stars of the same mass,implying that they provide an excellent fit to the recent gravitational wavedata GW170817 of LIGO and Virgo. The assumptions underlying the viability ofthe different star types, in particular those corresponding to absolutelystable quark matter, are finally discussed at some length.
