We examine which first order phase transitions are consistent with today'sastrophysical constraints. In particular, we explore how a well-constrainedmass-radius data point would restrict the admissible parameter space and tothis end, we employ the most likely candidates of the recent NICER limits ofPSR J0030+0451. To systematically vary the stiffness of the equation of state,we employ a parameterizable relativistic mean field equation of state, which isin compliance with results from chiral effective field theory. We model phasetransitions via Maxwell constructions and parameterize them by means of thetransitional pressure $p_{\rm trans}$ and the jump in energy density$\Delta\epsilon$. This provides us with a generic setup that allows for rathergeneral conclusions to be drawn. We outline some regions in the $p_{\rmtrans}$-$\Delta\epsilon$ parameter space that may allow for a phase transitionidentification in the near future. We also find that a strongly constraineddata point, at either exceptionally large or small radii, would reduce theparameter space to such an extent that mass and radius become insufficientindicators of a phase transition.

Which first order phase transitions to quark matter are possible in neutron stars?
