Quarkyonic stellar models are able to satisfy observed mass and radius constraints with a wide range of model parameters, avoiding the obligatory fine-tuning of conventional hybrid star models, including requiring the transition density to be very close to the nuclear saturation density.

We find that the tidal deformability and 90$\%$ credible interval is $\tilde{\Lambda}=310^{+679}_{-234}$ for a uniform component mass prior, $\tilde{\Lambda}=354^{+691}_{-245}$ for a component mass prior informed by radio observations of Galactic double neutron stars, and $\tilde{\Lambda}=334^{+669}_{-241}$ for a component mass prior informed by radio pulsars.
