Impact of the PSR J0740+6620 radius constraint on the properties of high-density matter
Isaac Legred, Katerina Chatziioannou, Reed Essick +2
X-ray pulse profile modeling of PSR J0740+6620, the most massive known pulsar, with data from the NICER and XMM-Newton observatories recently led to a measurement of its radius. We…
Constraints on the maximum mass of neutron stars with a quark core from GW170817 and NICER PSR J0030+0451 data
Ang Li, Zhiqiang Miao, Sophia Han +1
We perform a Bayesian analysis of the maximum mass of neutron stars with a quark core, incorporating the observational data from tidal deformability of the GW170817 b…
Combining Electromagnetic and Gravitational-Wave Constraints on Neutron-Star Masses and Radii
Mohammad Al-Mamun, Andrew W. Steiner, Joonas Nättilä +6
We perform a joint Bayesian inference of neutron-star mass and radius constraints based on GW170817, observations of quiescent low-mass X-ray binaries (QLMXBs), photospheric radius…
On the minimum radius of very massive neutron stars
Sophia Han, Madappa Prakash
Prospects of establishing the radii of massive neutron stars in PSR J1614-2230 and PSR J0740+6620 from NICER and Chandra observatories hold the potential to constrain the equation…
Constraining hadron-quark phase transition parameters within the quark-mean-field model using multimessenger observations of neutron stars
Zhiqiang Miao, Ang Li, Zhenyu Zhu +1
We extend the quark mean-field (QMF) model for nuclear matter and study the possible presence of quark matter inside the cores of neutron stars. A sharp first-order hadron-quark ph…
Studying strong phase transitions in neutron stars with gravitational waves
Katerina Chatziioannou, Sophia Han
The composition of neutron stars at the extreme densities reached in their cores is currently unknown. Besides nuclear matter of normal neutrons and protons, the cores of neutron s…
