We summarize our current knowledge of neutron-star masses and radii. Recent instrumentation and computational advances have resulted in a rapid increase in the discovery rate and precise timing of radio pulsars in binaries in the past few years, leading to a large number of mass measurements. These discoveries show that the neutron-star mass distribution is much wider than previously thought, with three known pulsars now firmly in the 1.9–2.0-M⊙ mass range. For radii, large, high-quality data…

These are exciting times for binary black hole (BBH) research. LIGO and Virgo detections are progressively drawing a spectacular fresco of BBH masses, spins and merger rates. In this review, we
Spectral analysis of the quiescent low-mass X-ray binary in the globular cluster M30
We present a recent Chandra observation of the quiescent low-mass X-ray binary containing a neutron star (NS), located in the globular cluster M30. We fit the thermal emission from the NS to extract
The Equation of State for the Nucleonic and Hyperonic Core of Neutron Stars
Abstract We re-examine the equation of state for the nucleonic and hyperonic inner core of neutron stars that satisfies the 2M⊙ observations as well as the recent determinations of stellar radii
The millisecond pulsar mass distribution: Evidence for bimodality and constraints on the maximum neutron star mass
The mass function of neutron stars (NSs) contains information about the late evolution of massive stars, the supernova explosion mechanism, and the equation-of-state of cold, nuclear matter beyond
A New Constraint on the Nuclear Equation of State from Statistical Distributions of Compact Remnants of Supernovae
Understanding how matter behaves at the highest densities and temperatures is a major open problem in both nuclear physics and relativistic astrophysics. Our understanding of such behavior is often
First Demonstration of Early Warning Gravitational-wave Alerts
Gravitational-wave observations became commonplace in Advanced LIGO-Virgo’s recently concluded third observing run. 56 nonretracted candidates were identified and publicly announced in near real
Birth events, masses and the maximum mass of Compact Stars
We give in this Chapter an overview of the problem of neutron star mass distribution, the issue of the maximum mass as inferred from the existing sample and the new gravitational wave events, and the
Comprehensive Analysis of the Tidal Effect in Gravitational Waves and Implication for Cosmology
Detection of gravitational waves (GWs) produced by coalescence of compact binaries provides a novel way to measure the luminosity distance of GW events. Combining their redshift, they can act as
Potential Gravitational-wave and Gamma-ray Multi-messenger Candidate from 2015 October 30
We present a search for binary neutron star (BNS) mergers that produced gravitational waves during the first observing run of the Advanced Laser Interferometer Gravitational-Wave Observatory (LIGO),
Cooling of Small and Massive Hyperonic Stars
We perform cooling simulations for isolated neutron stars using recently developed equations of state for their core. The equations of state are obtained from new parametrizations of the FSU2


X-ray bursts
The observations and progress in the theoretical understanding of X-ray burst sources are reviewed. Of about 150 known low mass X-ray binary systems, X-ray bursts have been observed from about 50
Cosmic separation of phases
A first-order QCD phase transition that occurred reversibly in the early universe would lead to a surprisingly rich cosmological scenario. Although observable consequences would not necessarily
High-precision timing of millisecond pulsars. I - Astrometry and masses of the PSR 1855 + 09 system
The observing method, data-analysis procedures, and results of a 4.4-year series of timing observations of a binary millisecond pulsar PSR 1855 + 09 are presented. The spin parameters of the pulsar,
Variations on a theme by Skyrme: A systematic study of adjustments of model parameters
We present a survey of the phenomenological adjustment of the parameters of the Skyrme-Hartree-Fock (SHF) model for a self-consistent description of nuclear structure and low-energy excitations. A

Surface emission from neutron stars and implications for the physics of their interiors
Neutron stars are associated with diverse physical phenomena that take place in conditions characterized by ultrahigh densities as well as intense gravitational, magnetic and radiation fields.
A Catalog of Parameters for Globular Clusters in the Milky Way
A database of parameters for globular star clusters in the Milky Way is described which is available in electronic form through the WorldWideWeb. The information in the catalog includes up-to-date
