Polytropic fits of modern and unified equations of state
Lami Suleiman, Morgane Fortin, Julian-Leszek Zdunik +1
Equations of state for a cold neutron star's interior are presented in three-column tables that relate the baryonic density, the energy density, and the pressure. A few analytical…
Partially accreted crusts of neutron stars
Lami Suleiman, Julian-Leszek Zdunik, Pawel Haensel +1
Neutron stars in low-mass binary systems are subject to accretion. The common assumption in studying the properties of the neutron star crust is the fully accreted crust approximat…
Faint objects in motion: the new frontier of high precision astrometry
Fabien Malbet, Céline Boehm, Alberto Krone-Martins +83
Sky survey telescopes and powerful targeted telescopes play complementary roles in astronomy. In order to investigate the nature and characteristics of the motions of very faint ob…
Influence of the crust on the neutron star macrophysical quantities and universal relations
Lami Suleiman, Morgane Fortin, Julian Leszek Zdunik +1
Measurements of neutron-star macrophysical properties thanks to multimessenger observations offer the possibility to constrain the properties of nuclear matter. Indeed cold and den…
Thermal evolution of relativistic hyperonic compact stars with calibrated equations of state
Morgane Fortin, Adriana R. Raduta, Sidney Avancini +1
A set of unified relativistic mean-field equations of state for hyperonic compact stars recently built in [M. Fortin, Ad. R. Raduta, S. Avancini, and C. Providencia, Phys. Rev. D {…
Magnetic fields in late-stage proto-neutron stars
S. K. Lander, P. Haensel, B. Haskell +2
We explore the thermal and magnetic-field structure of a late-stage proto-neutron star. We find the dominant contribution to the entropy in different regions of the star, from whic…
Relativistic hypernuclear compact stars with calibrated equations of state
M. Fortin, A. R. Raduta, S. Avancini +1
Within the covariant density functional theory of hypernuclear matter we build a series of equations of state for hypernuclear compact stars, by calibrating the coupling constants…
Empirical constraints on the high-density equation of state from multi-messenger observables
Márcio Ferreira, M. Fortin, Tuhin Malik +2
We search for possible correlations between neutron star observables and thermodynamic quantities that characterize high density nuclear matter. We generate a set of model-independ…
Bulk viscosity in neutron stars with hyperon cores
D. D. Ofengeim, M. E. Gusakov, P. Haensel +1
It is well-known that r-mode oscillations of rotating neutron stars may be unstable with respect to the gravitational wave emission. It is highly unlikely to observe a neutron star…
ESA Voyage 2050 white paper -- Faint objects in motion: the new frontier of high precision astrometry
F. Malbet, U. Abbas, J. Alves +28
Sky survey telescopes and powerful targeted telescopes play complementary roles in astronomy. In order to investigate the nature and characteristics of the motions of very faint ob…
Hyperonic stars and the symmetry energy
Constança Providência, Morgan Fortin, Helena Pais +1
In the present study we analyse the effect of the density dependence of the symmetry energy on the hyperonic content of neutron stars within a relativistic mean field description o…
Fundamental physics and the absence of sub-millisecond pulsars
B. Haskell, J. L. Zdunik, M. Fortin +3
Observations of the spin distribution of rapidly rotating neutron stars show evidence for a lack of stars spinning at frequencies larger than Hz, well below the pred…
GW170817: constraining the nuclear matter equation of state from the neutron star tidal deformability
Tuhin Malik, N. Alam, M. Fortin +5
Constraints set on key parameters of the nuclear matter equation of state (EoS) by the values of the tidal deformability, inferred from GW170817, are examined by using a diverse se…
Hyperons in hot dense matter: what do the constraints tell us for equation of state?
M. Fortin, M. Oertel, C. Providência
For core-collapse and neutron star merger simulations it is important to have at hand adequate equations of state, describing the underlying dense and hot matter as realistically a…
Accurate ray tracing of realistic neutron star atmospheres for constraining their parameters
F. H. Vincent, M. Bejger, A. Rozanska +9
Thermal dominated X-ray spectra of neutron stars in quiescent transient X-ray binaries and neutron stars that undergo thermonuclear bursts are sensitive to mass and radius. The mas…
Thermal states of neutron stars with a consistent model of interior
M. Fortin, G. Taranto, G. F. Burgio +3
We model the thermal states of both isolated neutron stars and accreting neutron stars in X-ray transients in quiescence and confront them with observations. We use an equation of…

We derive analytic approximations for the neutrino luminosities and the heat capacities of neutron stars with isothernal nucleon cores as functions of the mass and radius of stars.…

The Theia Collaboration, Celine Boehm, Alberto Krone-Martins +96
In the context of the ESA M5 (medium mission) call we proposed a new satellite mission, Theia, based on relative astrometry and extreme precision to study the motion of very faint…
(No) neutron star maximum mass constraint from hypernuclei
M. Fortin, S. S. Avancini, C. Providência +1
(Abridged) The recent measurement of the mass of two pulsars has raised the question whether such large masses allow for the existence of exotic degrees of freedom, s…
