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…
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…
Classifications of Twin Star Solutions for a Constant Speed of Sound Parameterized Equation of State
Jan-Erik Christian, Andreas Zacchi, Jürgen Schaffner-Bielich
We explore the possible mass radius relation of compact stars for the equation of states with a first order phase transition. The low density matter is described by a nuclear matte…
Twin Stars within the SU(3) Chiral Quark-Meson Model
Andreas Zacchi, Laura Tolos, Jürgen Schaffner-Bielich
We present new stable solutions of the Tolman Oppenheimer Volkoff equations for quark stars using a quark matter equation of state based on the SU(3) Quark-Meson model that exhibit…
Compact stars in a SU(3) Quark-Meson Model
Andreas Zacchi, Rainer Stiele, Juergen Schaffner-Bielich
The recent observations of the massive pulsars PSR J1614-2230 and of PSR J0348+0432 with about two solar masses implies strong constraints on the properties of dense matter in the…
