The discovery of nondiffuse sources of gravitational waves through compact-object mergers opens new prospects for the study of physics beyond the Standard Model. In this paper, we study the effects of a new force between quarks, suggested by the gauging of baryon number, on pure neutron matter at supranuclear densities. This leads to a stiffening of the equation of state, allowing neutron stars to be both larger and heavier and possibly accommodating the light progenitor of GW190814 as a…

Neutron Stars with Baryon Number Violation, Probing Dark Sectors
The neutron lifetime anomaly has been used to motivate the introduction of new physics with hidden-sector particles coupled to baryon number, and on which neutron stars provide powerful constraints.


GW190814: Impact of a 2.6 solar mass neutron star on the nucleonic equations of state
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
Was GW190814 a Black Hole-Strange Quark Star System?
It is investigated the possibility that the low mass companion of the black hole in the source of GW190814 was a strange quark star, which could fulfill the presently available astrophysical and nuclear physics constraints which require a softer equation of state.
GW190814 as a massive rapidly rotating neutron star with exotic degrees of freedom
In the context of the massive secondary object recently observed in the compact-star merger GW190814, we investigate the possibility of producing massive neutron stars from a few different equation
The Possibility of the Secondary Object in GW190814 as a Neutron Star
A compact object was observed with a mass of by LIGO Scientific and Virgo collaborations (LVC) in GW190814, which provides a great challenge to investigations of supranuclear matter. To study this
Studying the onset of deconfinement with multi‐messenger astronomy of neutron stars
With the first multi-messenger observation of a binary neutron star merger (GW170817) new constraints became available for masses and radii of neutron stars. We introduce a class of hybrid EoS that
Effects of the equation of state on the bulk properties of maximally rotating neutron stars
Neutron stars are among the densest known objects in the universe and an ideal laboratory for the strange physics of super-condensed matter. While the simultaneously measurements of mass and radius
Heavy Magnetic Neutron Stars
We systematically study the properties of pure nucleonic and hyperonic magnetic stars using a density-dependent relativistic mean-field (DD-RMF) equations of state. We explore several parameter sets
A two-solar-mass neutron star measured using Shapiro delay
Radio timing observations of the binary millisecond pulsar J1614-2230 that show a strong Shapiro delay signature are presented and the pulsar mass is calculated to be (1.97 ± 0.04)M⊙, which rules out almost all currently proposed hyperon or boson condensate equations of state.
