Theoretical priors in scalar-tensor cosmologies: thawing quintessence

The late time acceleration of the Universe can be characterized in terms of an extra, time dependent, component of the universe -- dark energy. Expand abstract.

Neutron rich matter in the laboratory and in the heavens after GW170817

The historic observations of the neutron star merger GW170817 advanced our understanding of r-process nucleosynthesis and the equation of state (EOS) of neutron rich matter. Expand abstract.

Neutron star under homotopy perturbation method

We obtain a mass function solving the Tolman-Oppenheimer-Volkoff (TOV) equation for isotropic and spherically symmetric system via homotopy perturbation method (HPM). Expand abstract.

Combining magneto-hydrostatic constraints with Stokes profiles inversions

Inversion codes for the polarized radiative transfer equation can be used to infer the temperature $T$, line-of-sight velocity $v_{\rm los}$, and magnetic field $\rm{\bf B}$ as a function of the continuum optical-depth $\tau_{\rm c}$. Expand abstract.

Fast Rotating Relativistic Stars: Spectra and Stability without Approximation

The ultimate universal relations for asteroseismology are derived which can lead to relations involving the moment of inertia and Love numbers in an effort to uniquely constrain the equation of state via all possible observables. Expand abstract.

The Shock Physics of Giant Impacts: Key Requirements for the Equations of State

We discuss major challenges in modeling giant impacts between planetary bodies, focusing on the equations of state (EOS). Expand abstract.

Efectos del campo magn'etico en un gas de bosones vectoriales neutros: aplicaciones astrof\'isicas

In order to appropriately take into account the magnetic anisotropy in the equations of state of this object, we develope a system of equations to describe the hydrodynamic equilibrium -- the structure -- of spheroidal compact objects starting from an axisymmetric metric. Expand abstract.

Implications of the fermion vacuum term in the extended SU(3) Quark Meson model on compact stars properties

We study the impact of the fermion vacuum term in the SU(3) quark meson model on the equation of state and determine the vacuum parameters for various sigma meson masses. Expand abstract.

Contact Geometry and Thermodynamics of Black Holes in AdS

In addition, the equations of state of general black holes in AdS are shown to emerge from the high temperature ideal gas limit equations, via suitable deformations induced by contact vector fields. Expand abstract.
