Description

In this work, we focus on identifying which conditions generate massive stars and how these affect the radii and tidal deformability of intermediate and massive stars. We build equations of state either from realistic models with exotic degrees of freedom or in a model-independent approach, using a functional form of the speed of sound and discuss cross-overs, first-order phase transitions, and different kinds of twin-star solutions. We focus on the implications of GW190814 as a neutron-star constraint, but also discuss GW170817, J0030+0451, J0740+6620, and the binary companion to V723 Mon.
