Nuclear matter properties and neutron star structures from an extended linear sigma model
Yao Ma
The properties of nuclear matter and the structures of neutron stars are analyzed with a baryonic extended linear sigma model in mean-field approximation, where the masses of baryo…
Neutron star structure and nuclear matter properties from a general Walecka-type model with Bayesian analysis
Yao Ma, Jia-Ying Xiong
We establish a Bayesian analysis framework with a general Walecka-type relativistic mean-field model to study dense nuclear matter under constraints from nuclear matter properties…
Hadronic description of nuclear matter and neutron star properties
Yao Ma, Yong-Liang Ma, Jia-Ying Xiong
The composition of the neutron star is one of the most fundamental and long-standing problems in nuclear- and astro-physics. The known properties of nuclear matter, together with t…
Composition of scalar mesons and their effects on nuclear matter properties in an extended linear sigma model
Yao Ma, Yong-Liang Ma
It has been argued that the iso-scalar and iso-vector mesons play significant roles in nuclear matter and neutron star structures. We improve the extended linear sigma model with b…
White Dwarf Structure and Binary Inspiral Gravitational Waves from Quantum Hadrodynamics
Ling-Jun Guo, Yao Ma, Yong-Liang Ma +2
White dwarfs, one of the compact objects in the universe, play a crucial role in astrophysical research and provide a platform for exploring nuclear physics. In this work, we exten…
Peak of sound velocity, scale symmetry, and nuclear force in baryonic matter
Lu-Qi Zhang, Yao Ma, Yong-Liang Ma
The sound velocity in homogeneous matter has fundamental significance as it relates to the stiffness of the equation of state of compact star matter. In this work, we investigate t…
