Approximate Universal Relations for Neutron Stars and Quark Stars
Abstract Neutron stars and quark stars are ideal laboratories to study fundamental physics at supra nuclear densities and strong gravitational fields. Astrophysical observables, however, dependExpand
PSR J0030+0451 Mass and Radius from NICER Data and Implications for the Properties of Neutron Star Matter
Neutron stars are not only of astrophysical interest, but are also of great interest to nuclear physicists because their attributes can be used to determine the properties of the dense matter inExpand
A Massive Pulsar in a Compact Relativistic Binary
Introduction Neutron stars with masses above 1.8 solar masses (M☉), possess extreme gravitational fields, which may give rise to phenomena outside general relativity. These strong-field deviationsExpand
Tidal Love Numbers of Neutron Stars
For a variety of fully relativistic polytropic neutron star models we calculate the star's tidal Love number k2. Most realistic equations of state for neutron stars can be approximated as a polytropeExpand
I-Love-Q: Unexpected Universal Relations for Neutron Stars and Quark Stars
TLDR
The findings suggest that the moment of inertia, the Love number, and the quadrupole moment obey universal relationships that are independent of the internal structure of the stars, implying that measurements of one of the three could accurately predict the other two. Expand
A two per cent Hubble constant measurement from standard sirens within five years
TLDR
It is shown that additional gravitational-wave detections by LIGO and Virgo can be expected to constrain the Hubble constant to a precision of approximately two per cent within five years and approximately one per% within a decade. Expand
Gravitational-Wave Astronomy with Inspiral Signals of Spinning Compact-Object Binaries
Inspiral signals from binary compact objects (black holes and neutron stars) are primary targets of the ongoing searches by ground-based gravitational-wave interferometers (LIGO, Virgo, and GEO-600).Expand
Approximate Universal Relations among Tidal Parameters for Neutron Star Binaries
One of largest uncertainties in nuclear physics is the relation between the pressure and density of supranuclear matter: the equation of state. Some of this uncertainty may be removed through futureExpand
A gravitational-wave standard siren measurement of the Hubble constant
TLDR
A measurement of the Hubble constant is reported that combines the distance to the source inferred purely from the gravitational-wave signal with the recession velocity inferred from measurements of the redshift using the electromagnetic data. Expand
A two-solar-mass neutron star measured using Shapiro delay
TLDR
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. Expand
