Abstract We systematically investigate the mergers of neutron star–white dwarf binaries from beginning to end, with a focus on properties inflows and outflows in accretion disks their electromagnetic emissions. Using population synthesis models, we determine subset these which white companion undergoes unstable mass transfer complete tidal disruption, forming large disk around star. The material evolves according one-dimensional advection-dominated accretion-disk model nuclear burning,...

Nuclear pasta is an exotic form of nuclear matter that occurs in the crust neutron stars below saturation density. Various structures with cylindrical, planar, and more complicated geometries evolve from Coulomb lattice nuclei immersed a fluid neutrons. Such should not only affect how star cools rotates but also height ``mountains'' can sustain---potentially detectable as persistent sources gravitational waves. By performing large set quantum calculations authors show energy landscape...

FleCSPH is a smoothed particle hydrodynamics simulation tool, based on the compile-time configurable framework FleCSI. The asynchronous distributed tree topology combined with fast multipole method allows to efficiently compute and long range particle-particle interactions. provides initial data generators, relaxation techniques, standard evolution drivers, which can be easily modified extended user-specific setups. Data input/output uses H5part format, compatible modern visualization software.

In this contribution we extend the recently developed two-flavor quark-matter string-flip model by including strange quarks. We discuss implications for compact stars.

In this contribution, we outline a new 2-phase description of the quark-nuclear matter hybrid equation state that takes into account effects phase space occupation (excluded volume) in both, hadronic and quark phases. For nuclear phase, reduction available volume at increasing density leads to stiffening, while for effective string tension confining functional is obtained. The deconfinement transition resulting sensitive both excluded effects. As an application, consider under compact star...

Studying compact star binaries and their mergers is integral to determining progenitors for observable transients. Today, compact-star are typically studied via state-of-the-art computational fluid dynamics codes. One such numerical technique, Smoothed Particle Hydrodynamics (SPH), frequently chosen its excellent mass, energy, momentum conservation. The natural treatment of vacuum the ability represent highly irregular morphologies make SPH an tool study mergers. For many scenarios,...

Neutron star mergers are cosmic catastrophes that produce some of the most energetic observed phenomena: short gamma-ray bursts, gravitational wave signals, and kilonovae. The latter optical transients, powered by radioactive nuclides which synthesized when neutron-rich ejecta a disrupted neutron undergoes decompression. We model this decompression phase using data from simulations post-merger accretion disk winds. use smoothed particle hydrodynamics with realistic nuclear heating to...

Medical devices and systems are increasingly relying on software using artificial intelligence (AI) machine learning (ML) algorithms to increase efficiency, provide better diagnoses, the quality of care for patients. AI- ML-based have an advantage over traditional medical device because they designed learn improve large databases actual or simulated patient data. However, use these datasets could introduce harmful biases certain populations, restrict economic development if policy were...

Smoothed particle hydrodynamics (SPH) is positioned as having ideal conservation properties. When properly implemented, of total mass, energy, and both linear angular momentum guaranteed exactly, up to machine precision. This particularly important for some applications in computational astrophysics, such binary dynamics, mergers, accretion compact objects (neutron stars, black holes, white dwarfs). However, astrophysical that require the inclusion gravity, calculating pairwise interactions...
