Is the secondary component of GW190814 the lightest black hole or the heaviest neutron star ever discovered in a double compact-object system [R. Abbott et al., ApJ Lett., 896, L44 (2020)]? This is the central question animating this letter. Covariant density functional theory provides a unique framework to investigate both the properties of finite nuclei and neutron stars, while enforcing causality at all densities. By tuning existing energy density functionals we were able to: (a) account for… Expand

Rapidly rotating Δ-resonance-admixed hypernuclear compact stars
Abstract We use a set of hadronic equations of state derived from covariant density-functional theory to study the impact of their high-density behavior on the properties of rapidly rotatingExpand
Probing the Nuclear Equation of State from the Existence of a ∼2.6 M⊙ Neutron Star: The GW190814 Puzzle
This work examines possible constraints on the nuclear equation of state inferred from the consideration that the low mass companion is a slow or rapidly rotating neutron star, and systematically studies the tidal deformability of a possible high mass candidate existing as an individual star or as a component one in a binary neutron star system.
