Impact of massive neutron star radii on the nature of phase transitions in dense matter

Understand

The last few years have seen tremendous progress in the observation of the global properties of neutron stars (NSs), e.g.

• masses, radii and tidal deformabilities.
• Such properties provide information about possible phase transitions in the inner cores of NSs, provided the connection between observed masses and radii and the equation of state (EoS) is well understood.
• We focus the present study on first-order phase transitions, which often softens the EoS and consequently reduces the maximum mass as well as the radii of NSs.
