The origin of the first neutron star – neutron star merger [PDF]
Astronomy & Astrophysics, 2018 The first neutron star-neutron star (NS-NS) merger was discovered on August 17, 2017 through gravitational waves (GW170817) and followed with electromagnetic observations. This merger was detected in an old elliptical galaxy with no recent star formation. We perform a suite of numerical calculations to understand the formation mechanism of this merger.

The Emergence of a Lanthanide-rich Kilonova Following the Merger of Two Neutron Stars [PDF]
, 2017 We report the discovery and monitoring of the near-infrared counterpart (AT2017gfo) of a binary neutron-star merger event detected as a gravitational wave source by Advanced Laser Interferometer Gravitational-wave Observatory (LIGO)/Virgo (GW170817) and ...

Tidal Deformabilities and Radii of Neutron Stars from the Observation of GW170817. [PDF]
Physical Review Letters, 2018 We use gravitational-wave observations of the binary neutron star merger GW170817 to explore the tidal deformabilities and radii of neutron stars.

Neutron Star Matter and Neutron Star Models
Zeitschrift für Naturforschung A, 1974 Various methods to study the ground state of neutron star matter are compared and the corresponding neutron star models are contrasted with each other. In the low density region ρ < 1014gr cm-3 the nuclear gas is treated here by means of a Thomas Fermi method and the nuclei are described by the droplet model of Myers and Swiatecki.

Continuous Gravitational Waves from Neutron Stars: Current Status and Prospects [PDF]
Universe, 2019 Gravitational waves astronomy allows us to study objects and events invisible in electromagnetic waves. It is crucial to validate the theories and models of the most mysterious and extreme matter in the Universe: the neutron stars.

Magnetic, thermal and rotational evolution of isolated neutron stars [PDF]
Living Reviews in Computational Astrophysics, 2019 The strong magnetic field of neutron stars is intimately coupled to the observed temperature and spectral properties, as well as to the observed timing properties (distribution of spin periods and period derivatives).

Phase transitions in neutron stars and their links to gravitational waves [PDF]
Journal of Physics G: Nuclear and Particle Physics, 2019 The recent direct observation of gravitational wave event $GW170817$ and its $GRB170817A$ signal has opened up a new window to study neutron stars and heralds a new era of Astronomy referred to as the Multimessenger Astronomy.

Studying strong phase transitions in neutron stars with gravitational waves [PDF]
Physical Review D, 2019 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 stars might harbor exotic matter such as deconfined quarks.

Thermal evolution and quiescent emission of transiently accreting neutron stars [PDF]
Astronomy & Astrophysics, 2019 Aims. We study the long-term thermal evolution of neutron stars in soft X-ray transients (SXTs), taking the deep crustal heating into account consistently with the changes of the composition of the crust.
