Phase Transition Phenomenology with Nonparametric Representations of the Neutron Star Equation of State

Reed Essick, Isaac Legred, Katerina Chatziioannou +2

Astrophysical observations of neutron stars probe the structure of dense nuclear matter and have the potential to reveal phase transitions at high densities. Most recent analyses a…

-modes of neutron stars with hadron-to-quark crossover transitions

Constantinos Constantinou, Sophia Han, Prashanth Jaikumar +1

We perform the first study of the principal core -mode oscillation in hybrid stars containing quark matter, utilizing a crossover model for the hadron-to-quark transition inspir…

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…

Treating quarks within neutron stars

Sophia Han, M. A. A. Mamun, S. Lalit +2

Neutron star interiors provide the opportunity to probe properties of cold dense matter in the QCD phase diagram. Utilizing models of dense matter in accord with nuclear systematic…

Cooling of neutron stars in soft X-ray transients

Sophia Han, Andrew W. Steiner

Thermal states of neutron stars in soft X-ray transients (SXRTs) are thought to be determined by "deep crustal heating" in the accreted matter that drives the quiescent luminosity…
