CompOSE (CompStar Online Supernovae Equations of State) is an online repository of equations of state (EoS) for use in nuclear physics and astrophysics, e.g., in the description of compact stars or the simulation of core-collapse supernovae and neutron-star mergers, see http://compose.obspm.fr. The main services, offered via the website, are: a collection of data tables in a flexible and easily extendable data format for different EoS types and related physical quantities with extensive documentation and referencing; software for download to extract and to interpolate these data and to calculate additional quantities; webtools to generate EoS tables that are customized to the needs of the users and to illustrate dependencies of various EoS quantities in graphical form. This manual is an update of previous versions that are available on the CompOSE website, at arXiv:1307.5715 [astro-ph.SR], and that was originally published in the journal "Physics of Particles and Nuclei" with doi:10.1134/S1063779615040061. It contains a detailed description of the service, containing a general introduction as well as instructions for potential contributors and for users. Short versions of the manual for EoS users and providers will also be available as separate publications.

  1. The petit four of color-superconducting phases in proto-neutron star evolution

    nucl-th 2026-07 conditional novelty 6.0

    Along constant-baryon-number cooling tracks, color-superconducting cores in proto-neutron stars follow four scenarios, with stable cold CSC only in a narrow high-mass band for the chosen EoS.

  2. GRACE: An Open-Source Framework for GPU-Accelerated Numerical Relativity

    gr-qc 2026-07 accept novelty 6.0

    GRACE is a validated, open-source, Kokkos+p4est GPU-portable framework that evolves ideal GRMHD with constrained transport self-consistently coupled to Z4c Einstein equations on fixed or adaptive meshes.

  3. A Physics Informed Bayesian Neural Network for the Neutron Star Equation of State

    astro-ph.HE 2026-04 unverdicted novelty 6.0

    A physics-informed Bayesian neural network learns neutron-star equations of state from theoretical priors and constraints, then generates posterior mass-radius and mass-tidal-deformability distributions consistent wit...

  4. Properties of the neutron star crust informed by nuclear structure data

    nucl-th 2025-05 unverdicted novelty 6.0

    Bayesian NS EoS study using full nuclear posterior distributions and consistent crust modeling finds increased surface thickness and crustal moment of inertia relative to prior work.

  5. Relativistic Mean Field Approach with Chiral Symmetry Breaking and Quark Confinement in the light of Astrophysical Observations

    nucl-th 2026-07 conditional novelty 5.0

    RMF-CC models with ωρ coupling better match multi-messenger NS data and LQCD/NEP constraints than the baseline, yet standard RMF remains preferred without core phase transitions, requiring high Ksat ~300 MeV.

  6. The crust of dark-matter admixed neutron stars: bulk properties and torsional oscillations

    gr-qc 2026-06 unverdicted novelty 5.0

    Dark matter admixed neutron stars show up to 12% thinner crusts and higher torsional oscillation frequencies than pure neutron stars when dark matter forms a core, with analytical formulas matching numerics at sub-per...

  7. Bulk viscosity from neutron decays to dark baryons in neutron star matter

    astro-ph.HE 2025-09 conditional novelty 5.0

    Neutron dark decays modify the equation of state and either mildly suppress or strongly enhance bulk viscosity in neutron star merger conditions, depending on the in-medium decay rate.

  8. Core Composition Effects on the QCD Axion Mass Limit from Neutron Star Cooling

    hep-ph 2026-06 unverdicted novelty 4.0

    Varying neutron star core composition with hyperons and Delta resonances mildly affects the QCD axion mass limit from cooling, potentially bringing the DFSZ limit into the IAXO sensitivity window.

  9. Magnetized neutron stars: perturbative versus fully-numerical approaches

    astro-ph.HE 2026-05 conditional novelty 4.0

    Direct comparison of Konno-99 perturbative and LORENE numerical methods for poloidal magnetized neutron stars shows perturbative validity for observed fields up to ~10^16 G and numerical resolution limits below ~10^10 G.

  10. Studying the QCD Matter produced in Heavy-Ion Collisions using the MUSES Calculation Engine

    nucl-th 2026-06 unverdicted novelty 3.0

    The MUSES Calliope engine computes multi-dimensional QCD equations of state, merges them consistently, and feeds them into viscous hydrodynamic simulations of heavy-ion collisions with movable critical points and crit...

  11. The equation of state for neutron stars

    nucl-th 2026-07 unverdicted

    A textbook-style review of the neutron-star equation of state covering the models, experimental and observational constraints, and open questions, with no new result claimed or derived.
