Confronting GW190814 with hyperonization in dense matter and hypernuclear compact stars. (arXiv:2007.09683v2 [astro-ph.HE] UPDATED) <a href="http://arxiv.org/find/astro-ph/1/au:+Sedrakian_A/0/1/0/all/0/1">Armen Sedrakian</a>, <a href="http://arxiv.org/find/astro-ph/1/au:+Weber_F/0/1/0/all/0/1">Fridolin Weber</a>, <a href="http://arxiv.org/find/astro-ph/1/au:+Li_J/0/1/0/all/0/1">Jia-Jie Li</a> We examine the possibility that the light companion in the highly asymmetric binary compact object coalescence event GW190814 is a hypernuclear star. We use density functional theory with functionals that have been tuned to the properties of $Lambda$ hypernuclei as well as astrophysical constraints placed by the masses of the most massive millisecond pulsars, the mass-radius range inferred from the NICER experiment, and the binary neutron star merger event GW170817. We compute general-relativistic static and maximally rotating Keplerian configurations of purely nucleonicRead More →
