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.

Nucleosynthesis in low-mass stars: Shedding light on the cosmic origin of heavy elements [PDF]
EPJ Web of ConferencesLow-mass, low-metallicity stars while evolving through the asymptotic giant branch (AGB) phase undergo significant nucleosynthesis producing the majority of slow (s-) and intermedite (i-) neutron capture elements.

Herschel and Spitzer observations of slowly rotating, nearby isolated neutron stars
, 2014 Supernova fallback disks around neutron stars have been discussed to influence the evolution of the diverse neutron star populations. Slowly rotating neutron stars are most promising to find such disks.

Axisymmetric general relativistic hydrodynamics: Long-term evolution of neutron stars and stellar collapse to neutron stars and black holes [PDF]
, 2003 We report a new implementation for axisymmetric simulation in full general relativity. In this implementation, the Einstein equations are solved using the Nakamura-Shibata formulation with the so-called cartoon method to impose an axisymmetric boundary ...

New Constraints on Radii and Tidal Deformabilities of Neutron Stars from GW170817. [PDF]
Physical Review Letters, 2018 We explore in a parameterized manner a very large range of physically plausible equations of state (EOSs) for compact stars for matter that is either purely hadronic or that exhibits a phase transition.

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.

The Magnetospheres of (Accreting) Neutron Stars
EPJ Web of Conferences, 2014 I give an overview of the most important observational tools to study the magnetospheres of accreting neutron stars, with a focus on accreting neutron stars in high mass X-ray binary systems.

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.
