Gravitational quadrupole deformation and the tidal deformability for stellar systems: (The number of) Love for undergraduates
Andreas Zacchi
This article is intended for undergraduate students with the aim to provide a pedagogical introduction to the physics of stellar tidal deformations. The spherically symmetric shape…
Implications of the fermion vacuum term in the extended SU(3) Quark Meson model on compact stars properties
Andreas Zacchi, Juergen Schaffner-Bielich
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. We examin…
Signals in the tidal deformability for phase transitions in compact stars with constraints from GW170817
Jan-Erik Christian, Andreas Zacchi, Jürgen Schaffner-Bielich
We compute the tidal deformabilities for neutron star merger for equations of state with a strong first order phase transition producing a new separate branch in the mass-radius di…
Relativistic parameterizations of neutron matter and implications for neutron stars
Nadine Hornick, Laura Tolos, Andreas Zacchi +2
We construct parameter sets of the relativistic mean-field model fitted to the recent constraints on the asymmetry energy and the slope parameter for pure neutron matter. W…
The VO: A powerful tool for global astronomy
Christophe Arviset, Mark Allen, Alessandra Aloisi +14
Since its inception in the early 2000, the Virtual Observatory (VO), developed as a collaboration of many national and international projects, has become a major factor in the disc…
